350nm to 2500nm Center Wavelength Narrow Band Pass Optical Filter
Optical Bandpass Filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. HTOE Optical Bandpass Filters are ideal for a variety of applications, such as spectroscopy, fluorescence microscopy, clinical chemistry, or imaging. These filters are typically used in industrial, life science, or R&D industries.
Based on the technology of all-medium hard film coating and the principle of medium interference, the optical properties of narrow-band filters are independent of the thickness of the substrate. The narrow-band filters produced by HTOE are more convenient for the built-in imaging system instrument by improving the optical performance and fulfilling the application. The special optical material base is used to solve the problems of fogginess and instability of optical performance of traditional absorption synthetic glass. The products are manufactured according to the customer's requirements.
