Professional Sharp Cut Filters for Industrial Applications
HOYA CANDEO sharp cut filters are long-pass optical glass filters designed to block shorter wavelengths of light and allow longer wavelengths to pass. Within the wavelength range of approximately 350 nm to 800 nm, these filters selectively remove unwanted short-wavelength light—such as ultraviolet and blue—helping improve contrast, reduce scattering, and enhance image clarity for optical, inspection, and imaging applications.
Key Features:
- High-precision wavelength cutoff
- Industrial-grade optical quality
- Standard 50×50mm square format
- 2.5mm thickness for durability
- Suitable for imaging systems, inspection equipment, and optical analysis
Available Series:
- L Series (L37-L42): Long wavelength pass filters
- Y Series (Y44-Y52): Yellow range filters
- O Series (O54-O58): Orange range filters
- R Series (R60-R72): Red range filters
