I need integrating sphere diameter 3m, opening aperture 1m with base stand.
The internal coating is barium sulphite with uniformity 98.5%. Thermal stability of barium sulphite coating shuld be above 100 degree centigrade.
In addition to this, i need reference light source bulb for calibration,
along with bromine tungsten lamp+Halogen Lamp with 1000w/m2. The light flux shuld be variable by adjusting power supply. Futhermore, Spectroradiometer working range is 400-950nm. It will also included optcal power meter (such as
Newport 918D-UV-OD3R) to measure light density.
I have checked your equipment is only designed for white LED, can you provide the solution in 350-1050nm range

The Purpose of equipment is radiometric calibration of satellite camera.
