636DIB25 25 mm Dia. Standard Interference Bandpass Filter 636nm
The 636DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 636nm wavelength range while blocking other wavelengths. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is made from UVFS MAL-1965, a material specifically chosen for its optical properties in the visible light spectrum. It has a base shape of a circle, a standard geometry for optical components due to its uniform distribution of light. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing optical distortion.
The 636DIB25 has a Cut-On wavelength of 631nm and a Cut-Off wavelength of 641nm, meaning it begins transmitting light at 631nm and stops transmitting at 641nm. The Central Wavelength (CWL) is 636nm, the midpoint of the transmission range, providing a precise and narrow band of transmitted light.
Both the front and back of the filter are coated with KNI 636DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing surface reflections and increasing transmission efficiency.
The filter's shape is a Thin Lens, a design that minimizes optical aberrations and distortions, ensuring the transmitted light is as close to the original source as possible. This filter is currently in stock and available for immediate purchase through the vendor's website.
