Description
Our 940nm Optical Bandpass Filter is a premium optical bandpass filter designed to isolate a specific band of wavelengths from the total spectrum. This is achieved by providing a band of high transmission and bands of high rejection of spectral energy on both the long and short wavelength sides of the transmission band. This meticulous design ensures that the filter delivers optimal performance in various applications.
Customization of optical bandpass filters is at the heart of our offering. We understand that each project has unique requirements, which is why the size and shape of our bandpass filter products can be customized to meet specific needs. Our team is ready to assist with any inquiries and provide detailed spectral graphs or additional information to ensure you have all the necessary data for your decision-making process.
