84-712 25 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=3 mm 650nm

The 84-712 is a high-performance shortpass filter, designed and manufactured by Edmund Optics, a leading global provider of optical components. This filter, with a 25 mm diameter and a thickness of 3 mm, is specifically engineered for applications requiring short wavelength transmission and long wavelength rejection.

The filter's primary function is to allow light with wavelengths up to 650nm to pass through while blocking or reflecting wavelengths beyond this point. This characteristic is known as the cutoff wavelength, which is a critical parameter in the selection of optical filters. The 84-712 has a cutoff wavelength of 650nm, making it suitable for applications where short wavelength transmission is required.

The 84-712 filter features a hard coating on both the front and back surfaces, denoted as 'edm 84-699'. This coating enhances the filter's durability and resistance to environmental factors, ensuring longevity and reliability in various operating conditions.

The filter's geometry, with a diameter of 25mm and a thickness of 3mm, is designed to fit standard optical systems. The thin lens shape allows for easy integration into existing setups, making it a versatile choice for a wide range of applications.
