Engineering the future of 3D Microfabrication and microsystems
NS THz Filters
At Nielson Scientific LLC, we aim to provide innovative solutions for the science and technology industry. Our Terahertz Filters will provide solutions to every section of a variety of industries.
Applications
Terahertz Filters
Results through Micro-Scale Ablation
At Nielson Scientific LLC, we have developed a rapid, low-cost manufacturing capability for THz filters based on our proprietary nano-ablation process. This approach allows us to eliminate slow and expensive photolithography-based fabrication steps and use lower-cost, high-performance starting materials.
Features
- Custom high-pass filters, low-pass filters, and band-pass filters range from 0.1 to 10 THz
- High transmittance 60%-90%
- Unwanted wavelengths are reflected rather than absorbed
- Extremely thin metal layers (100 nm to 1 µm)
- Fabricated on thin dielectric layers (typically 8 µm polypropylene)
- Custom aperture sizes up to 600 mm.
Performance
Nielson Scientific designs and manufactures passive filters for Terahertz and Far IR wavelengths. The metallic microstructures are designed with specific resistance, capacitance, and inductance which creates microscopic circuits which resonate with specific wavelengths, allowing those to transmit, but act as a mirror for unwanted wavelengths.
The plot to the left is an example of the bandpass performance you can expect.
