Product Introduction

The JY-JFIOS-D500 belongs to a bottom-incident integrating sphere irradiation light source system. The sphere cavity is coated with PTFE reflective diffuse coating, with a spectral range of 250–2500 nm. The system is equipped with a multi-channel discrete ultraviolet LED light source array, where light sources of different bands can be independently controlled. After sufficient homogenization by the integrating sphere, a highly uniform ultraviolet irradiation field is generated at the light output port. The equipment integrates a light-proof dark box, motorized diaphragm, adjustable sample stage, and active cooling unit to suppress environmental light interference and light source thermal drift, ensuring high-precision and high-repeatability irradiation experiments. It is mainly used in ultraviolet photometry, material photo-irradiation durability studies, optoelectronic device calibration, photochemical experiments, and other scientific and industrial testing fields.

 

Product Features

Multi-Band Ultraviolet LED Combined Light Source: Equipped with 8-band ultraviolet LED light sources, covering UVC, UVB, and UVA regions. Each band can be independently controlled, meeting the needs of ultraviolet irradiation aging, photosensitivity testing, and material UV response experiments.

 

Ultra-High Uniform Irradiation Field: PTFE highly diffusely reflective inner walls mix light multiple times, providing an output surface uniformity of >98%, ensuring uniform ultraviolet irradiation across the sample surface and avoiding experimental errors caused by local light intensity differences; output light stability reaches ±0.2%, ensuring high repeatability in long-term experiments.

 

Enclosed Light-Proof Dark Box Design: The entire system integrates a light-proof box to block environmental stray light interference without requiring an additional darkroom; the built-in adjustable sample stage allows free adjustment of sample distance, accommodating samples of different sizes.

 

Complete Cooling System: Each LED light source is equipped with an independent cooling fan to continuously dissipate heat, suppressing light source temperature drift and ensuring stable irradiance during long-term continuous operation. The motorized adjustable diaphragm allows precise control of light flux.

 

Broad-Spectrum Coating Substrate: The PTFE coating operates within 250–2500 nm. Beyond the ultraviolet range, it can also expand to visible and near-infrared light source solutions, providing strong device compatibility.
