Optical filters selectively transmit light of a specific wavelength range while blocking light of the remaining wavelengths. From everyday photography to advanced scientific research, filters are critical in a wide range of applications.

Filter products are mainly categorized according to spectral bands, spectral characteristics, film layer materials, application characteristics, and other ways. Spectral band: ultraviolet filters, visible filters, infrared filters; Spectral characteristics: bandpass filters, cut-off filters, spectral filters, neutral density filters, reflection filters.

Optical Glass 900nm Short Pass Filter

Plano convex lens has a positive focal length and is usually used for aiming and focusing of monochromatic light sources, converging parallel light, or converting divergent point light sources into parallel light. Its main functions in optical systems include beam expansion, imaging, beam collimation.

Powell lenses are optical marking prisms that allow laser beams to pass through and be optimally drawn into a straight line with uniform optical density, good stability, and good linearity, which can eliminate the central hot spot and fading edge distribution of Gaussian beams, which is suitable for various biomedical, automotive assembly, food processing and other machine vision applications.
