Product Description
10/5 To 60/40 520nm Optical Glass Filters, Short Pass Filter For Optical Instruments
The 10/5 To 60/40 520nm Optical Glass Filters, Short Pass Filter For Optical Instruments is a precision-engineered optical component designed to transmit wavelengths below 520 nm while effectively blocking longer wavelengths in the visible and near-infrared spectrum. This short-pass filtering characteristic makes it highly valuable in optical systems where spectral separation, signal enhancement, and contrast improvement are required.
Manufactured using high-grade optical glass substrates with advanced multilayer interference coatings, the filter ensures sharp spectral cut-off characteristics and high transmission efficiency in the passband region. The surface quality options of 10/5 to 60/40 scratch-dig levels provide flexibility for different optical system requirements, from high-end scientific instrumentation to industrial optical devices.
The 520 nm cut-off point is particularly important in applications involving green fluorescence suppression, RGB spectral separation, and optical calibration systems. By blocking wavelengths above 520 nm, the filter enhances imaging clarity, reduces background noise, and improves detection sensitivity in optical instruments. This makes it suitable for both laboratory-grade systems and industrial optical setups requiring stable and repeatable spectral performance.
Application Fields
- Optical Imaging Systems: Enhancing contrast in scientific and industrial imaging devices
- Fluorescence Microscopy: Isolating excitation and emission wavelengths below 520 nm
- Spectroscopy Instruments: Improving wavelength discrimination and measurement accuracy
- Machine Vision Systems: Increasing detection precision by filtering unwanted spectral noise
- Laser Systems: Used for wavelength selection and optical signal conditioning
- Research Laboratories: Optical experiments requiring precise spectral separation
