ODM Optical Bandpass Filter 200nm - 1100nm Wavelength Range Optical Long Pass Filter
We specialize in customizing longpass filters with high cut-off in the short-wave region and high penetration in the long-wave region according to customer requirements. The wavelength range from ultraviolet to near infrared can be selected arbitrarily, with a transition zone slope between projection and reflection of less than 20 nm.
Manufactured from high-quality quartz glass with vacuum-deposited hard coating, our filters can withstand flame burning tests. These filters are commonly used in laser photon beauty instruments, optical instruments, infrared imaging, and various other applications.
