740FDL12 12.5 mm Dia. Longpass Dichroic Filter 750nm

The 740FDL12 is a Dichroic Filter, specifically a Longpass Filter with a 750nm cut-on wavelength, sourced from Knight Optical. This filter is designed with a circular geometry, featuring a 12.5mm diameter and a thickness of 1.1mm. The material composition of the filter is N-BK7 Schott, a widely used optical glass known for its excellent optical properties and durability.

The filter's primary function is to transmit light at wavelengths above 750nm while reflecting or absorbing wavelengths below this value. This makes it an ideal component for various applications, such as beam combining, fluorescence microscopy, and other scenarios requiring precise wavelength selection.

The coating on both the front and back surfaces of the filter is KNI 740FDL-0, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance and durability, ensuring reliable and consistent operation in its intended application.

The filter is designed in a Thin Lens shape, which can be beneficial in applications where minimal optical path deviation is required. This shape also contributes to the filter's overall compactness and ease of integration into optical systems.

According to the vendor's information, the filter is currently in stock and available for immediate purchase. Further details, including pricing and shipping information, can be found on the Knight Optical website using the provided weblink.
