The 12-254 is a 25 mm diameter Longpass Filter, specifically designed for use with 248.6nm laser lines. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website. The filter is currently in stock, ensuring quick and efficient delivery.
The filter is made from UVFS MAL-1965, a material specifically chosen for its optical properties. It has a base shape of a circle, a standard geometry in optical applications. The filter's thickness is 3.5mm, providing sufficient structural integrity while minimizing optical distortion.
The 12-254 filter is designed to cut on at 248.6nm, allowing light of this wavelength and longer to pass through. The cut-off wavelength is 0nm, meaning that it will allow all wavelengths longer than 248.6nm to pass through. This makes it ideal for applications where specific wavelength filtration is required.
Both the front and back of the filter are coated with EDM 12-254, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance and durability, ensuring reliable operation in a variety of conditions.
The filter is shaped as a Thin Lens, a common shape in optical elements. This shape allows for easy integration into existing optical systems, making the 12-254 a versatile and practical choice for a wide range of applications.
