LP770nm filter is a precision optical long wave pass filter with a cut-off wavelength in the near-infrared region of 770nm, which can effectively cut off visible and ultraviolet light, and has high transmission in the near-infrared band above 770nm. It is widely used in machine vision, biomedical and scientific research fields.
This product adopts advanced coating technology and has steep transition band characteristics (15-30nm). The cut-off depth can reach OD4-OD6, and the passband transmittance exceeds 90%. The substrate is made of high-quality optical glass or fused silica to ensure excellent environmental stability and durability.
The main applications include near-infrared imaging systems, semiconductor wafer inspection, agricultural product quality analysis, fluorescence microscopy, deep imaging of living tissues, night vision monitoring, and laser wavelength purification. In the biomedical field, the LP770nm filter can fully utilize the NIR-I optical window (700-900nm) to achieve deeper tissue penetration and lower light damage.
When selecting, it is necessary to comprehensively consider the characteristics of the light source, the requirements of the system signal-to-noise ratio, and the working environment conditions. We provide standard specifications and customized services to meet the precision optical needs of different application scenarios.
