Holographic gratings are formed by an interference fringe field of two laser beams whose
standing wave pattern is exposed to a polished substrate coated with photoresist. Processing
of the exposed medium results in a pattern of straight lines with a sinusoidal cross section.
Holographic gratings produce less stray light than ruled gratings. They can also be produced
with up to 3600 grooves per millimeter for greater theoretical resolving power.

Transmission Gratings are designed to disperse incident light at specific angles. Angular dispersion
is a function of angle of incidence and groove spacing. Dispersion increases as angle of incidence
increases or as groove spacing decreases. Coarse groove spacing maintains high efficiency
while fine groove spacing reduces transmission at long wavelengths resulting in low efficiency.
Transmission gratings offer low polarization sensitivity as opposed to reflection gratings because
incident light is not reflected by a mirror coating such as aluminum. Since light is transmitted
through the grating, transmission gratings can be used in compact, in-line configurations. They are
ideal for use in monochromators and spectrometers.

Transmission grating beamsplitters are commonly used for laser beam division and multiple
laser line separation in visible wavelengths. The transmitted beam is diffracted into multiple
orders. Our transmission grating beamsplitters consist of an index matched epoxy replica on
a polished glass substrate, for a high total efficiency. Several gratings are available, offering
different dispersion and power distributions. The diffraction angle for any wavelength may be
calculated using the grating equation for normal incident light.

Interference Filters (FWHM>10nm)
CWL See details in the list FWHM Tolerance See details in the list
CWL Tolerance See details in the list Transmission See details in the list
FWHM See details in the list Blocking Depth λc ≤ 1090 nm; better than OD4@200~1200nm
λc ＞1090 nm; better than OD4@200~2500nm
The transmitted band of bandpass filter is surrounded by two cut-off bands. They are used
to pass through partial wavelength and block all other wavelengths. Bandpass Filters are
ideal for many applications, such as spectroscopy, clinical chemistry, or imaging. Golden Way
provides a variety of half-bandwidth bandpass interference filter with a variety of transmission
and sizes to suit your application.

Longpass filters provide a wide blocking bandwidth, high blocking depth, high transmission
and sharp slope. They are widely used in fluorescence excitation spectrum measurement,
Raman spectrum, spectral group and astronomical observation applications. When
combining with our shortpass filters, they can be used to set up variable bandwidth bandpass
filters system. We also provide mounted filters which can be easily used in the optical system.

Longpass filters provide a wide blocking bandwidth, high blocking depth, high transmission
and sharp slope. They are widely used in fluorescence excitation spectrum measurement,
Raman spectrum, spectral group and astronomical observation applications. When
combining with our shortpass filters, they can be used to set up variable bandwidth bandpass
filters system. We also provide mounted filters which can be easily used in the optical system.

T refers to transmission.
These filters have constant density values across the surface. The transmission to reflection
ratio varies with density selection. In stacks, the total density is the sum of each filter’s
density. ND filters are used primarily for the attenuation of light over a wide spectral range.
They are often used in laser and photometer applications, where excessive power can cause
damage or inaccurate results. Orient mirrored side toward source at 0° angle of incidence.

These filters possess level spectral transmittance characteristics in the visible region and
attenuate light by absorption with minimal reflection comparing with reflective ND filters.
Typically, neutrality and density of absorptive filters are a function of the material and the
thickness. They are useful in light control applications for measuring instruments and
exposure control in imaging. Spectral variations occur as optical density increases. Optical
Density exhibits an additive relationship; for example, stacking filters with OD values of 0.6 and
0.9 yields a resultant density of 1.5.

Dichroic Shortpass Filters are designed for a 45° of incidence. The rejected light is reflected
at 90°, making such filters ideal for fluorescence applications or spectral beamsplitters. The
filters feature low polarization dependence, broad spectral ranges.

Thickness Tolerance ±0.2mm Blocking Depth Tmax <1%; Tavg <0.1%
IR filters can transmit light of a specific spectrum while cutting off other unwanted light. Such
filters are widely used in environmental monitoring, safety detection, and FLIR applications.
For example, for gas analysis such as carbon dioxide (CO2), methane (CH4), carbon monoxide
(CO), ammonia (NH3), water (H2O), ethanol (CH3CH2OH), sulfur dioxide (SO2), nitrous oxide
(N2 O), etc.

Beijing Golden Way Scientific Co., Ltd. has increased the stock sales of wave plates in order to meet the
needs of universities, research institutes and optical instrument manufacturers.
A waveplate is an optical element that can generate an additional optical path difference (or phase
difference) between two mutually perpendicular light vibrations. Usually made of birefringent wafers
such as quartz, calcite or mica of precise thickness, with the optical axis parallel to the wafer surface. The
corresponding phase retardation is obtained by picking different wafer thicknesses.
Waveplates are classified according to their structure, including multiple-order wave plates, glued zeroorder wave plates or compound zero-order wave plates and true zero-order wave plates.The wave plate is
divided into: 1/4 wave plate (Quarter Waveplate) according to the retardation.
Half Waveplate.
When linearly polarized light is incident on the quarter-wave plate at an angle of 45°, the outgoing light will
become circularly polarized light.
When linearly polarized light is incident on the half-wave plate, the outgoing light is still linearly polarized,
but the vibration direction of the transmitted light will be rotated from the original azimuth by 2θ (θ is the
angle between the incident light and the optical axis of the crystal).

Glued Zero Order Waveplate is made of two multiple order waveplates. Comparing with single
multiple waveplates, such technic could decrease the sensitivity of waveplate retardance to
wavelength and incident angle. Our glued zero order waveplates are made of quartz crystals
and the retardance includes λ/2 and λ/4. For applications with a greater than +/-1% deviation,
zero order waveplates are recommended due to their increased bandwidth and lower
sensitivity to temperature change.

Laser Prisms are used to redirect laser beams in a number of beam steering or beam manipulation applications.
Laser Prisms use a variety of substrates, coatings, or a combination of the two to achieve high reflectivity of a particular range of wavelengths. Laser
Prisms are designed to internally reflect a laser beam off of multiple surfaces in order to redirect the beam path. Laser Prisms come in several types
including right angle, or retroreflector varieties designed for different kinds of beam deviation.
Laser Grade Right Angle Prisms which feature excellent surface quality and surface flatness, could provide high damage thresholds allowing for
easy integration into most Nd:YAG laser systems. Low arcsecond level angle tolerance and are made from precision H-K9L and UV fused silica,
making them ideal for laser based applications requiring precise alignment.Right angle prisms are generally used to bend image paths or redirect
light at 90° . This produces a left handed image and depending on the orientation of the prism, the image may be inverted or reverted. Right angle
prisms can also be used in combination for image or beam displacement.

The right angle prisms are typically used to bend the image path or turn the light path 90°
，combing two right angle prisms also can combine the image and deflect the beam.
We suggest that you use the right angle prisms with Hypotenuse aluminum coated for the
application of large AOI. We offer a wide range of right angle prisms for your application.
