The 750FSX40-25 is a high-performance bandpass filter developed by Andover Corporation, a leading vendor in the optical industry. This filter, with a circular base shape and thin lens design, is specifically designed for applications that require a narrow passband around the 750nm wavelength.
The filter boasts a 25mm diameter and a thickness of 5.9mm, making it suitable for a wide range of optical systems. The 750FSX40-25 is part of Andover's High-Transmitting Bandpass Filter series, which is known for its high transmission and excellent out-of-band rejection.
The filter's physical data includes a cut-on wavelength of 730nm and a cut-off wavelength of 770nm, with a central wavelength (CWL) of 750nm. This means that it allows light within this narrow band to pass through while effectively blocking light outside this range.
The 750FSX40-25 is coated with Andover's proprietary coatings on both the front and back surfaces, further enhancing its performance. The coating details are not provided in the item data, but typically, these coatings are designed to reduce reflection, increase transmission, and protect the filter from environmental factors.
