What is working principle for the laminated Infrared Bandpass Filters?
This laminated infrared band-pass filter combines the dual strengths of a dielectric film filter and absorbing infrared glass. The dielectric membrane filter allows us to define the center wavelength and bandwidth of the passband according to application requirements. Meanwhile, the HWB series infrared transmittance glass, with its excellent absorption properties, delivers a superior cutoff effect in the cutoff region. In addition, the black infrared glass can be placed on the outside of the lens, so it conceals the interior from view.
What is typical application for laminated infrared bandpass filters?
The laminated infrared band-pass filter combines the dual characteristics of a coated filter and an absorption-type filter, making it widely applicable. Typical application for glued bandpass filter is very broad, including Biomedical & In-Vitro Diagnostic Instruments, Industrial Machine Vision & Automated Inspection, Scientific Optical Measurement & Spectroscopy, Lighting, Indicator & Consumer Optics, Laser Auxiliary & Optoelectronic Modules, Small-Scale Astronomical & Remote Sensing.
Shenzhen Hengda Liyuan Optoelectronics introduced advanced optical technology that apply depositing nano materials through ion-assisted evaporation onto a multilayer hard film in a high vacuum environment which coating layer is firm and has good tightness, and small bandwidth drift. Liyuan optoelectronics have been focus on optical coating for more than 17 years and offer one-stop optical filters solution including Narrow Bandpass Filters, IR cut-off Filters, Longpass & Short Filters, Notch Filters, ND filters, Star filters and Optical sapphire block.
Other typical Bandpass filters in stock from Liyuan Optoelectronics include BP410 BP420 BP430 BP440 BP450 BP460 BP470 BP480 BP490 …etc.
