Custom 92% High Transmistance Optical 650nm 850nm 940nm IR BandPass Filter Glass
Bandpass filters are optical components designed to transmit light within a specific wavelength range while blocking light outside this range. They are widely used in various applications, including spectroscopy, fluorescence microscopy, and remote sensing. The 650/850/940nm bandpass filters are specifically designed to allow light to pass through at wavelengths of 650nm, 850nm, and 940nm, respectively.
Specification:
| Surface Quality | 60/40 |
| Tolerence | +-0.01mm |
| Transmistance | above 92% |
| FWHM | 10nm to 85nm upon request |
| Mounted | Thread Mounted as Require |
| Samples | Available |
650nm Bandpass Filter
- Wavelength Range: Typically centered around 650nm, with a bandwidth that can vary depending on the specific application.
- Applications:
- Fluorescence Microscopy: Used to isolate the red fluorescence emitted by certain fluorophores.
- Spectroscopy: Useful for analyzing the spectral characteristics of materials that emit or absorb light in the red region.
- Optical Sensing: Employed in sensors that detect specific wavelengths in the red spectrum.
850nm Bandpass Filter
- Wavelength Range: Centered around 850nm, with a narrow bandwidth to ensure high selectivity.
- Applications:
- Infrared Imaging: Commonly used in near-infrared (NIR) cameras and imaging systems.
- Telecommunications: Utilized in fiber optic communication systems to filter out unwanted wavelengths.
- Biomedical Applications* Used in medical imaging and diagnostics, such as in blood oxygenation measurements.
940nm Bandpass Filter
- Wavelength Range: Centered around 940nm, with a precisely defined bandwidth.
- Applications:
- Night Vision and Security Systems Often used in night vision cameras and security systems to enhance visibility in low-light conditions.
- Remote Sensing: Used in satellite and aerial imaging to capture specific spectral information.
- Biometric Sensors: Employed in devices that use near-infrared light for biometric authentication, such as facial recognition systems.
