BCI offers custom IR/THz wire grids that reflect electric fields parallel to tungsten wires and transmit the perpendicular component. Published wire diameters are 13, 18 or 25 µm, with typical 0.250 mm spacing and customer-selected frames up to the stated 304.8 mm size. The supplier describes controlled assembly/packaging and spacing inspection. Its above-50 µm suitability and 20 µm–10 mm range need configuration-specific validation; no independent optical acceptance was recovered.
Technical detail
Core features
Parallel reflection and perpendicular transmission mechanism
13/18/25 µm tungsten wires and typical 0.250 mm spacing
Custom variable spacing and customer-selected frame materials
Supplier ISO Class 7 assembly/inspection and Class 4 packaging; microscope/vision checks
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Currently advertised custom product. Supplier optical-performance and controlled-environment claims lack independently inspected configuration acceptance; SCIEX ion-path grids are not proof of this polarizer use.
Commercial availability
Custom wire, spacing and frame enquiries through BCI; wavelength, geometry, measured optical performance and acceptance must be agreed.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.

B.C. Instruments offers free-standing IR/THz polarizers using parallel tungsten wires secured to a customer-designed mounting frame. It states wire diameters 13, 18 and 25 microns, typical spacing 0.250 mm with variable spacing possible, maximum frame diameter/side 304.8 mm, and metal/composite/ceramic frame materials. Electric fields parallel to wires are reflected and perpendicular fields transmitted. This is a distinct optical product offering, without independent delivered-configuration acceptance.

The supplier states ISO Class 7 grid assembly/final inspection, Class 4 packaging, digital-microscope FOD/trimming inspection and vision-system spacing/parallelism checks. It describes the grids as best suited above 50 microns yet gives a 20-micron–10-mm wavelength range and greater-than-99.9-percent polarization claim. These screening statements require wavelength/configuration-specific confirmation; clean-room descriptions are not recovered current clean-room certificates.
