12-281 25 mm Dia. High Performance Laser Line Bandpass Filter; t=2mm 1030nm

The 12-281 is a high-performance laser line bandpass filter, designed and manufactured by Edmund Optics. This filter, with a diameter of 25 mm, is specifically engineered for use with a central wavelength of 1030 nm, making it ideal for applications that require precise filtering within this spectrum.

The filter is constructed from N-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This material ensures the filter's durability and reliability, making it suitable for a wide range of optical applications.

The filter's geometry is defined by a diameter of 25 mm and a thickness of 2 mm, providing a robust and compact design. The thin lens shape further enhances its usability, allowing for easy integration into various optical systems.

The coating of the filter is another notable feature. Both the front and back surfaces are coated with EDM 12-273, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance, providing superior blocking capabilities and high transmission efficiency.

The filter's physical data includes a center wavelength of 1030 nm, which is the specific wavelength that the filter is designed to pass. This makes it ideal for applications that require precise wavelength selection.
