89-675 25 mm Dia. High Performance OD 4.0 Shortpass Filter; t=3 mm 1250nm
The 89-675 is a high-performance shortpass filter, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This filter has a 25 mm diameter and a thickness of 3 mm, making it suitable for a wide range of applications. The filter features a hard-coated surface, enhancing its durability and resistance to wear and tear.
The 89-675 filter is designed to transmit light with wavelengths up to 1250 nm, while effectively blocking light with longer wavelengths. This makes it ideal for applications where short wavelength light needs to be isolated or emphasized. The filter's physical data includes a cut-on wavelength of 0 nm and a cut-off wavelength of 1250 nm, ensuring precise control over the light spectrum.
The filter's coating is another key feature. Both the front and back surfaces of the filter are coated with EDM 89-671, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance and durability, ensuring reliable and consistent operation even under demanding conditions.
The filter's shape is thin lens, which is a design that minimizes optical aberrations and distortions, further enhancing its performance. The catalog number for this filter is 89-675, and it is currently in stock, according to the vendor's website.
