The 14-030 is a 25 mm diameter Low GDD Dichroic Shortpass Ultrafast Filter, specifically designed for use at a wavelength of 588nm. This filter is sourced from the reputable optical vendor, Edmund Optics, and is available for purchase through their website.
The filter is a Dichroic type, which means it selectively reflects or transmits light based on its wavelength. In this case, it is designed to pass wavelengths shorter than 950nm and block those longer than this value. This makes it ideal for applications where short wavelength light needs to be isolated or emphasized.
The filter is circular in shape, with a diameter of 25mm, and has a thickness of 1.05mm. This makes it suitable for use in a wide range of optical systems, including those where space is at a premium.
The filter's coating is a critical component of its performance. Both the front and back surfaces of the filter are coated with the EDM 14-030 coating, which is specifically designed to enhance its shortpass filtering capabilities. This coating is applied using advanced techniques to ensure high uniformity and durability.
The filter's physical data includes a cut-on wavelength of 0nm and a cut-off wavelength of 950nm. This means that it begins to transmit light at 0nm and stops transmitting at 950nm. This sharp cut-off is a key feature of the filter, making it ideal for precise wavelength selection.
The filter is shaped as a Thin Lens, which means it has been designed to focus light. This can be useful in a variety of applications, including imaging and beam shaping.
