Material: ZnSe (Zinc Selenide) Diameter: 5mm Height: 2 mm What is a ZnSe Roof Prism?A ZnSe Roof Prism (also known as a Zinc Selenide Roof Prism or IR Roof Mirror) is a type of reflective optical prism that inverts and reverses an image by 90 degrees. It is widely used in infrared optical systems and laser alignment devices. VY Optics manufactures precision ZnSe roof prisms with high transmission in the infrared spectrum, suitable for thermal imaging, CO₂ laser systems, and spectroscopy instruments. FAQ / People Also Ask Q1: What is the function of a ZnSe Roof Prism?A ZnSe Roof Prism reflects and rotates an image by 90°, commonly used in laser and infrared systems to redirect beams precisely. Q2: Why use Zinc Selenide (ZnSe) as the material?ZnSe offers excellent transmission in the infrared region (0.6–18 µm) and low absorption, making it ideal for CO₂ laser and IR applications. Q3: Can ZnSe Roof Prisms be AR coated?Yes, anti-reflective (AR) coatings can be applied to improve transmission and reduce surface reflection losses. Q4: What are the size options available?Standard sizes include 5 mm, 10 mm, and 20 mm prisms. Custom dimensions and angles are available upon request. How to Choose the Right Optical PrismChoosing the right optical roof prism depends on the material, wavelength range, coating, and application. ZnSe is a preferred choice for infrared systems due to its high transmission and durability. Factors to Consider:Wavelength Range: Select a material that matches your laser or IR wavelength. Surface Quality: Ensure precision polishing for stable beam alignment. Coating Type: AR or HR coatings optimize transmission and reflection as needed. Size & Geometry: Choose a prism dimension that fits your optical system design. Environment: Consider operating temperature and humidity conditions.

PBS beamsplitter prism Prisms 100optics
Material [Shared by the standard/high-precision columns; Original cell colspan2]: N-BK7.Fused Silica,N-SF11,or depend on request Clear Aperture [Standard specification]: ≥85 % Dimension Tolerance [Standard specification]: ±0.1 mm
A polarizing beamsplitter separates incident unpolarized light into two orthogonal linearly polarized beams. P-polarized light is fully transmitted, while S-polarized light is reflected at 45 degrees and exits at 90 degrees to the P beam. Made from a pair of cemented high-precision right-angle prisms, with a polarizing beamsplitter dielectric coating on the hypotenuse of one prism.

Triangular Prism Prisms 100optics
Material: K9 or ZF glass, etc. Dimensional Tolerance [Two original parallel options without grade distinctions]: ±0.2，±0.1 Surface Quality: 60 / 40
Prisms turn and displace light at specified angles and can adjust image orientation. Their shape and function depend on their interaction with light. Incident light may reflect from one or more surfaces before exiting, or refract while passing through the substrate. Baijing offers forms including triangular prisms, pentaprisms, Dove prisms, Powell prisms, roof prisms, and corner cubes.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
