Filter

Overview

IdealPhotonics' optical filters are optical elements that selectively transmit or reflect light waves of specific wavelengths (or frequencies) to control the spectral composition of light.They allow light of the target wavelength band to pass through while blocking or attenuating other unwanted wavelengths, thereby achieving the filtering, enhancement, or suppression of optical signals.

Terahertz Bandpass Filter

The Terahertz Bandpass Filter is a high-performance device specifically designed for the terahertz frequency range, capable of effectively addressing the filtering challenges in this band. The product adopts a specially designed perforated metal film structure, achieving precise filtering performance in the terahertz region. Featuring a narrow bandwidth, high transmission, and excellent out-of-band suppression, the filter also offers significant advantages such as a large optical aperture, compact structure, and lightweight design. It provides reliable technical support for terahertz imaging, spectroscopy, and communication systems.The filter consists of a series of specially designed metal films with perforations, whose structural dimensions are determined by the required frequency point. Customization is available to meet specific application requirements, with selectable center frequencies covering a range from 0.3 THz to 7 THz. These metal films are mounted on metal rings inside a cylindrical metal housing. The housing is made of aluminum alloy with a black anodized finish.To prevent contamination and physical damage, white or transparent polymer membranes are applied to both sides, ensuring a sufficiently large effective optical aperture while enhancing device signal-to-noise ratio. Two types of effective optical apertures are available:Round: standard clear aperture/outer diameter Φ54 mm / Φ64 mmSquare: standard clear aperture 60 mm × 60 mm / outer diameter Φ100 mm(All dimensions can be customized.)Additionally, the product supports customization of the optical aperture to meet demanding requirements for special optical paths or higher energy throughput. A clear product label is attached to the housing surface, indicating key information such as product model and center frequency.

Near-Infrared Filters

A near-infrared filter is an optical component that selectively transmits or blocks light in the near-infrared wavelength range. It is primarily classified into absorption-type filters relying on material absorption and thin-film-type filters relying on interference effects, and is used in imaging, sensing, detection, and other scenarios.
