Bentham manufactures an extensive range of integrating
diameter, for measuring the total lux
and spectral power distribution of almost any light source (from
lasers and LEDs to large linear fluorescent tubes).
Diffuse reflection and transmission integrating spheres
with specular light traps are also available. Our spheres are
also routinely used as uniform light sources.
Our spheres can be manufactured from ODM, a proprietary
PTFE type material, barium sulphate or gold coated depending
on the wavelength range required:
BenFlect: best performace 200-2500nm
Barium sulphate: general purpose 300-2500nm
Gold: recommended for IR applications beyond 2000nm
