Main features High reflectivity: It has extremely high reflectivity at 650nm wavelength to ensure that light of a specific wavelength does not leak.Broadband transmission: It allows light of other non-target bands to pass through, which is suitable for applications that separate specific wavelengths.Durability: High-quality coating…
Spectral Range Reflection Range: 355-415 nm mirrors generally have a reflectivity between 99% and 99.9%, with excellent reflection in the 355 to 415 nm range, while other wavelengths may have lower reflectivity to avoid unnecessary interference.Spectral Control: This mirror is designed for UV to near-visible…
Key Features Customized Geometries: These mirrors may have unique shapes, including freeform surfaces, asymmetric curves, or non-standard polygons. This flexibility allows them to direct or focus light according to precise application requirements, supporting functions like beam shaping, wide-angle reflection, and field-of-view expansion. Tailored Reflective Coatings:…

How an Infrared Variable Neutral Density Filter Works The IR VND filter typically consists of two polarizing films or elements with adjustable relative rotation. The filter’s density—and thus the level of light attenuation—can be varied by rotating these polarizing elements relative to each other. In…
A polarizing film is an optical filter that selectively transmits light with a specific polarization while blocking other orientations. This film is designed to either absorb or reflect light waves with certain orientations, thereby creating a polarized output. Polarizing films are widely used in applications…
Product parameters Features Splitting ratio: 40:60 beam splitter distributes the incident light in a ratio of 40% transmission and 60% reflection, which is suitable for occasions where asymmetric distribution of light energy is required.Wide spectral range: This beam splitter can be designed for different spectral…
The SP705 short-wave filter is actually an infrared cutoff filter. Its core function is to block infrared light above 705nm and only transmit visible light. This filter is specially designed to block infrared light above 705nm, effectively suppressing the passage of long-wave light and ensuring…
