The Light Ports Integrating Sphere brochure details customizable sizes, high‑reflectivity BaSO4 coating, and uniformity performance for optical measurements.
The Light Ports Integrating Sphere is a high‑stability, high‑reflectance optical diffuser used to improve measurement reproducibility. Light entering the sphere is uniformly reflected and diffused, providing a consistent output beam regardless of input angle, polarization, or spatial distribution.
The sphere is available in diameters from 5 cm to 100 cm, with custom aperture locations and optional dual‑opening designs for large samples. An auxiliary 10 W halogen lamp can be mounted for self‑absorption correction, and a quick‑change LED fixture enables fast sample exchange. The product offers >96% reflectance, <3% output uniformity variation, and a damage threshold of 1.5 J/cm² at 532 nm. This manual is written in Chinese.
| BaSO4 coating thickness | 0.5 mm |
|---|---|
| Reflectance | >96% (380–1100 nm) |
| Output port uniformity | Variation <3% across area |
| Typical sphere diameter example | 80 mm |
| Damage threshold | 1.5 J/cm² at 532 nm YAG laser |
The sphere provides a reflectance greater than 96 % over the 380 nm to 1100 nm wavelength range.
The output port uniformity variation is less than 3 % across the measurement area.
Integrating spheres are offered in diameters from 5 cm up to 100 cm, with custom aperture sizes and positions.
Yes, a 10 W halogen lamp can be mounted on the sphere wall for self‑absorption correction during measurements.
