IR-Cut SP700 Shortpass Filter
- ModelSP700
- SpecificationCustomizable
- MaterialOptical glass
Description
The SP700 shortpass filter achieves extreme transmission across the visible spectrum (400–700 nm) and deep blocking in the near-IR (730–1100 nm). With 700 nm as the spectral boundary, its steep transition and average transmission above 95% ensure high brightness and saturation of color reproduction, while T<0.1% blocking (customizable) in 730–1100 nm removes IR thermal noise and color shifts — the core 'de-IR' element of high-end optical systems.
