490SP 17 mm Dia. Surface Coating; Shortpass Filter Surface Coating

The 490SP is a high-quality shortpass filter developed by Omega Optical, a renowned vendor in the optical industry. This filter, with a catalog number of 3004, is specifically designed for use in applications where short wavelengths need to be efficiently passed while longer wavelengths are blocked.

The filter has a circular shape with a diameter of 17 mm and a thickness of 2 mm, making it compatible with a wide range of optical systems. It is made from UVFS MAL-1965, a material known for its excellent optical properties.

The 490SP filter features a unique coating on both the front and back surfaces, denoted as OME 490SP. This coating is designed to enhance the filter's performance, ensuring efficient shortpass filtering. The cut-on wavelength is 0 nm, and the cut-off wavelength is 490 nm, providing a sharp transition between passed and blocked wavelengths.
