SP SERIES VISIBLE SHORTPASS NIR BLOCK FILTERS
Often thought of as “IR-cut” filters, Shortpass Filters are specifically designed to pass a broad spectrum of shorter wavelength light, while blocking longer visible (VIS) and near-infrared (NIR) wavelengths.
- 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
- Designed to have a sharp transition between shorter wavelengths (which are passed) and longer wavelengths (which are blocked)
- Peak transmission ≥90% (in most models)
- 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
