Infrared Plate Beamsplitters are critical components
in FTIR spectrometers, Interferometers, and other
IR-enabled devices. Both the Calcium Fluoride (CaF2)
design, with an operating wavelength range of 0,8 - 6
μm, and the Zinc Selenide (ZnSe) design, with a 2 - 20
μm wavelength range, are available in multiple sizes.
Infrared Plate Beamsplitters are designed for a 15 -
45° angle of incidence, providing easy integration into
any instrument’s geometry.

• High Laser Damage Thresholds
• Excellent Surface Quality
• Insensitive to Input Beam’s Polarization State
Laser Line Non-Polarizing Plate Beamsplitters are
ideal for use in demanding laser applications where
polarization control is critical. Laser Line Non-Polarizing
Plate Beamsplitters are coated with dielectric layers
to increase system performance while maintaining
high laser damage thresholds and the polarization
state of the input beam. The 1025 nm – 1095 nm
coating is designed for some of the industry’s most
popular pulsed lasers, including Nd:YAG, Yb:KGW,
and Yb:YAG.
• Wire Grid Technology
• Reflects S-Polarized Light, Transmits
P-Polarized Light
• Ideal for High Temperature Environments
Broadband Polarizing Plate Beamsplitters consist of a
thin layer of aluminum MicroWires adhered to a glass
window. These beamsplitters are an alternative and
economical substitute for ruled or holographic wire
grid polarizers. Providing exceptional image contrast
and uniformity, these beamsplitters are ideal for applications
requiring large angular apertures and high
throughput. Note: MicroWires are very fragile. Handle
these beamsplitters with care.
