Product Introduction

The JY-FOIS84 is a small universal integrating sphere with an inner diameter of 84mm. Its inner wall is coated with sintered PTFE diffuse reflection material, optimized for optical testing in the 200–2500nm UV wavelength range. The sphere is equipped with several standard optical ports to accommodate light source input, fiber optic collection, and detector installation. It can be used to build experimental platforms for optical flux measurement, spectral acquisition, sample reflection/transmission testing, and UV radiation calibration. It is widely used in UV optical laboratories, photoelectric detector calibration, UV LED performance testing, and as an accessory for spectroscopic analysis equipment.

 

Product Features

Sintered PTFE coating with excellent UV performance: Unlike ordinary sprayed PTFE, the sintered coating is dense and durable, offering up to 99% reflectivity in the 200–2500nm UV region. The coating is non-powdering and highly stable, making it ideal for deep UV and UV optical experiments.

 

Multi-angle, multi-channel standardized port layout: Openings at 0°, polar, 90°, and 180° enable flexible arrangement of incident light, samples under test, and receiving detectors. The 90° port integrates an SMA905 fiber interface, allowing direct connection to a spectrometer to build an integrated spectral acquisition system.

 

Highly flexible modular expansion capability: Standard flange covers allow unused ports to be sealed from light. The 5mm small-aperture flange can be replaced to accommodate small sensing components such as photodiodes or UV detectors. The number, diameter, and angle of the ports are customizable.

 

Compact, small-sized structure suitable for precision experimental platforms: The 84mm small sphere is compact and easy to place on optical platforms, in glove boxes, or inside UV-sealed dark boxes, making it suitable for collecting tiny UV optical signals from samples.

 

Low stray light and good light field homogenization: The spherical cavity with a highly diffuse reflective inner wall thoroughly mixes incident light to form a uniform radiation field, reducing errors caused by uneven light spots.
