- SpecificationCustomizable
- MaterialOptical glass
Description
JYOPTO longpass filters transmit long wavelengths while blocking short wavelengths. Compared with conventional colored optical glass filters, our ion-assisted hard-coated longpass filters provide steeper cut-on, higher transmission and higher background optical density. The cut-on wavelength shifts toward shorter wavelengths as the incidence angle increases, allowing precise spectral tuning. Custom sizes, cut-on wavelengths, transmission and blocking depths are available on request.
Applications
- IPL hair removal, photorejuvenation and other beauty devices
- Fluorescence microscopy and biochemical analysis (emission filter)
- Machine vision and industrial inspection
- Multi-band police/forensic detection instruments
- Stage lighting and entertainment lighting color control
- Raman spectroscopy and spectral analysis (background suppression)
- Face/iris recognition and biometric terminals
- Infrared imaging, night vision and thermal cameras
