The "Series 250" is a liquid light guide suitable for the ultraviolet range, with the following specifications: - Transmission wavelength range: 220 to 650 nm - Usable in the UVC range It has a stable transmission rate in the UVC wavelength range, making it suitable for use as a light source in UV irradiators and in wafer manufacturing environments. Due to its material and structural characteristics, the liquid light guide possesses high transmission properties and minimizes light loss at the incident end face. Therefore, this product is suitable for cases requiring powerful UV light. 【Features】 - Transmission wavelength range: 220 to 650 nm - Usable in the UVC range - Low loss at the incident end face and high transmission rate - Flexible and no risk of breakage - Large acceptance angle (approximately twice that of silica fiber bundles)

LUMATEC's liquid light guide has the following strengths compared to fiber light guides that bundle fine wires: - Ultra-low loss: Minimal loss relative to the incident area. - No breakage: No breakage during bending since it does not use glass fibers. Additionally, it has a large acceptance angle, making it suitable for high-power light transmission applications. It supports connectors and sleeves that can be used for various applications, and branching types can also be manufactured. 【Specifications】 Core diameter [mm]: 3・5・8 N.A. 2α [°]: 50 Transmission wavelength range [nm]: 220–650 Total length [m] (max.): 5 Operating temperature range※ [°C]: +5 to +30
