エドモンド・オプティクス・ジャパン List of Products and Services

The pellicle beam splitter is bonded to an aluminum alloy frame (finished in black anodizing) with an extremely thin nitrocellulose film. Due to the very thin film, ghost images caused by unwanted back reflections from the rear side of the film are not observed. Mounting tap holes are provided at the 12 o'clock and 6 o'clock positions of the frame. While it is resistant to mechanical shocks and temperature fluctuations, care must be taken to avoid dust and spray. Do not touch the film under any circumstances (if cleaning is necessary, limit it to blowing away debris with weak compressed air). ■ The optical path lengths of incident light and reflected light are essentially the same ■ Ghost images from the rear side are essentially nonexistent ■ Chromatic aberration is practically negligible for converging/diverging beams ■ Pellicle thickness of 0.002mm *The catalog from Edmund Optics Japan can be downloaded from the link below.

Float glass is used as the substrate, and a metal film, dielectric multilayer film, or hybrid film is applied to its surface to achieve a specified R/T characteristic (generally, the 30R/70T type uses a metal (Inconel) film, the 70R/30T type uses a dielectric multilayer film, and the 50R/50T type uses a hybrid film). In visible light, it is divided into the following R/T ratios, with a small portion of light being absorbed. Designed for non-polarized light at a 45° incidence. A type with a single coat of MgF2 on the back side of the substrate is also available. This is effective in reducing ghost images. For inquiries about custom sizes or different R/T ratios, please contact our sales department. ■ Low-cost design ■ Multiple sizes available ■ A variety of R/T branching ratios available *You can download the catalog from Edmund Optics Japan that features this product from the link below.

The TECHSPEC plate beam splitter for VIS & NIR, ideal for dual magnification imaging systems and low-power laser beam combining, uses N-BK7 glass as the substrate, achieving a thin plate thickness through polishing while also ensuring high surface accuracy of the substrate. A dielectric multilayer film is applied to the surface side of the substrate to achieve a specified R/T division, significantly reducing energy loss compared to metal films. Additionally, a multi-AR coating is applied to the backside to suppress the generation of unwanted ghost images and maximize throughput. It is designed for non-polarized 45° incidence. ■ Non-polarized type beam splitter ■ Available in a type that functions in the visible light (VIS) range of 400-700nm and a type that functions in the near-infrared (NIR) range of 700-1100nm ■ A wide range of R/T ratios from 30/70 to 70/30 *You can download the catalog from Edmund Optics Japan that features this product from the link below.

The TECHSPEC cube beam splitter (non-polarizing type) is composed of two right-angle prisms. A suitable optical thin film is deposited on the sloped surface of one prism to function as a beam splitter, and the sloped surfaces of the two prisms are joined to form a cube shape. This film divides light at a specified ratio for both transmission and reflection at a wavelength of 550nm in the visible range when non-polarized light is incident. Since a dielectric multilayer film is used for the film that functions as the beam splitter, there is almost no light absorption loss due to the film itself (however, due to the difficulty of broad-band wavelength control with dielectric films, there may be different splitting ratios at the ends of the visible range). Additionally, a broad-band single-layer anti-reflection coating (MgF2 single) is applied to all four surfaces of the input/output faces, which is effective in reducing ghost images. ■ Non-polarizing type beam splitter ■ Dielectric multilayer film used for B/S coating ■ Three types of R/T ratios available *You can download the catalog from Edmund Optics Japan that features this product from the link below.
