Shortpass Filters
- Broad Transmission and Rejection Ranges
- Sharp Slope for Effective Spectral Discrimination
- Combine with Longpass Filter for Custom Bandpass Ranges
Shortpass filters are optical filters that allow short-wavelength light to pass while blocking longer wavelengths. They are commonly used in fluorescence imaging, machine vision, and other optical applications. Made from high-quality optical materials, these filters provide precise wavelength control and high transmission. Custom sizes and coatings are available to meet specific requirements.
