Import Band Pass Filter — Buy in Bulk from Supplier in Taiwan

The Band pass filter from Etafilm Technology Inc. is designed to transmit specific wavelengths of light while blocking others, making it essential for optical and telecommunications applications. Its precision-engineered construction ensures minimal distortion and high clarity, which is critical for fields like photography, fluorescence microscopy, and spectrometry. The filter’s durability allows it to maintain consistent performance across varying temperatures and environmental conditions.

Typical band pass filters in this category use substrates such as fused silica or borosilicate glass, with standard coatings like hard oxide or soft dielectric layers to achieve the desired spectral properties. The center wavelength (CWL) tolerance is usually ±2 nm for high-precision applications, and the full width at half maximum (FWHM) can range from 10 nm to 50 nm depending on the design. These filters are often categorized by their optical density, which typically exceeds OD 4 in the blocking range to ensure effective suppression of unwanted wavelengths.

Industries such as scientific research, medical diagnostics, and industrial quality control rely on these filters for accurate wavelength selection. Etafilm Technology Inc. supplies the filters with packaging suited for safe transport, and trade terms include FOB and CIF options. The company is based in Jhongli, Taoyuan, Taiwan, and operates as an imported-tier supplier with a harbor trust classification, catering to global buyers in optical and telecommunications sectors.
