THz Band Pass Filter
Product Introduction
THz Band Pass Filters allow electromagnetic waves within the wavelength range of 20 to 3000 μm to pass through. These filters are actually metal films with small holes, and the structure of the holes is determined by the specified wavelengths. This type of filter solves the transmittance problem of THz waves in the near-light wave band. This also enables the acquisition of higher purity THz waves with a large light transmittance aperture. When high spectral resolution and small appearance size and weight are required, it is recommended to use band pass filters.
THz Band Pass Filter Applications
- THz Spectroscopy
- Imaging
- THz Test Equipment
- Astronomy, Space and Aerospace Fields
- Materials Research
- Sensors and Detectors
- The Field Of Electro-Optics
THz Band Pass Filter Performance Features
- The passband range is from 0.1 to 15 THz (from 3000 to 20 μm)
- High transmittance rate within the passband range (60-90%)
- The transmittance rate is low outside the passband range(<4%)
- Can obtain components for the low-temperature stabilizer and the electro-optical equipment.
- Damage threshold (ranging from 0.1 to 15 THz) is - 65 - 100 W/cm2
