MF630-69 25 mm Dia. TXRED Emission Filter; CWL=630nm; BW=69nm

The MF630-69 is a 25 mm diameter Bandpass Filter, part of Thorlabs' extensive catalog of optical elements. This filter is designed with a Central Wavelength (CWL) of 630nm and a Bandwidth (BW) of 69nm, making it ideal for applications that require narrowband transmission in the TXRED emission spectrum.

The filter is constructed with a Circular base shape, ensuring uniformity in illumination and ease of integration into optical systems. It boasts a Thin Lens shape, which minimizes optical aberrations and enhances overall system performance. The filter's material ID, UVFS Mal-1965, is specifically engineered for optical applications, ensuring high-quality transmission and blocking characteristics.

The MF630-69 has physical data that includes a cut-on wavelength of 595.5nm and a cut-off wavelength of 664.5nm. This means that it begins transmitting at 595.5nm and stops transmitting at 664.5nm, effectively filtering out unwanted wavelengths. The filter's thickness is 3.5mm, providing robustness and durability while maintaining minimal optical path length distortion.

The front and back surfaces of the filter are coated with Thorlabs' proprietary coating, denoted as 'tho mf630-69'. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.
