High-Performance Optical Components by Z-Optics
Longpass filters are precision optical components designed to transmit wavelengths longer than a specified cutoff while blocking shorter wavelengths. These filters are essential in many advanced optical systems, providing excellent optical density (OD) and reliable wavelength selectivity over wide spectral ranges. Z-Optics offers a comprehensive range of longpass filters with various cut-on wavelengths, operational wavelength ranges, and standard dimension options to suit diverse industrial and scientific needs.
Our longpass filters deliver superior blocking of unwanted short wavelengths and high transmission efficiency in the longer wavelength region. This makes them ideal for applications requiring precise spectral separation and high contrast, such as fluorescence microscopy, spectroscopy, and laser systems. Available in multiple part numbers with cut-on wavelengths from 370 nm up to 1600 nm, and dimensions of 12.7 mm and 25.4 mm, Z-Optics longpass filters provide versatile options for custom and standard optical setups.
Applications of Z-Optics Longpass Filters
- Fluorescence Microscopy: Separating emitted fluorescence signals from excitation excitation light for enhanced imaging clarity and accuracy.
- Spectroscopy: Isolating specific longer wavelengths for material analysis, Raman spectroscopy, and multispectral imaging.
- Medical Imaging: Enhancing contrast by blocking UV and unwanted short wavelengths in devices like endoscopes and ophthalmic instruments.
- Laser Systems: Filtering out shorter wavelengths to ensure laser beam purity for medical, industrial cutting, or engraving applications.
- Environmental Monitoring: Infrared longpass filters aid in detecting heat signatures and atmospheric sensing by blocking visible light while transmitting IR radiation.
- Astronomy: Reducing effects of light pollution by filtering out shorter wavelengths to observe distant celestial bodies in specific spectral bands.
- Consumer Electronics: Improving image quality in cameras and smartphones by blocking haze-inducing short wavelengths and protecting eyes from harmful blue light.
