Shortpass Lens Filters
Shortpass Filters are commonly used in color imaging to achieve natural color rendering. They can also be used to protect the sensor from NIR laser damage or to reduce IR radiation or “camera bloom” created during hot metal or glass extrusion processes.
- Designed to have a sharp transition between shorter wavelengths (which are passed) and longer wavelengths (which are blocked)
- Peak transmission ≥90%*
- Can be used with Longpass Filters for a custom, fine-tuned Bandpass Filter
- Anti-reflection coated for maximum transmission
- Exceptional surface quality; 40/20 scratch/dig
- Available in wavelength ranges from 340nm to 785nm
Visible Shortpass Filters
- Separate colors in monochrome or color applications
- Improve contrast and resolution
Visible Shortpass NIR Block Filters
- Commonly placed over the camera’s image sensor to block NIR light and achieve natural color rendition
- Used as a hot mirror to reduce unwanted heat build-up caused by IR radiation
