530FDS25 25 mm Dia. Shortpass Dichroic Filter 530nm
The 530FDS25 is a high-quality dichroic filter, sourced from Knight Optical, designed for shortpass applications with a 530nm cutoff wavelength. This filter is circular in shape, featuring a 25mm diameter and a thickness of 1.1mm, making it suitable for a wide range of optical systems.
The filter is constructed from N-BK7 Schott glass, a popular choice due to its excellent optical properties and high damage threshold. The dichroic coating on both the front and back surfaces, denoted as 'kni 530fds-0', is designed to reflect wavelengths shorter than 530nm while transmitting longer wavelengths. This makes the 530FDS25 ideal for applications where short wavelength rejection is required.
The physical data of the filter indicates a cut-on wavelength of 750nm, ensuring effective shortpass filtering. The filter is currently in stock and available for immediate purchase through the Knight Optical website.
