The INS250 Integrating Sphere combines high throughput with an oversized diameter (254 mm) to minimize the effect of exit ports. The unit contains a built-in regulated power supply and calibrated standard lamp. The Kodak White Reflectance Coating (#6080) provides 97% reflectance from 450 to 900 nm. This barium sulfate formula is the most stable, durable, diffuse white reflectance coating available.
