ISC 积分球
ISC Integrating Spheres
商品货号:ECS000123
商品品牌:SPECTRAL PRODUCTS
详细介绍

            ISC系列积分球采用标准的反射膜层(工作波段400-2500nm),4个正交的接口(可选正交,8度或其它分布形式),壳体采用铸铝制成。

ISC Integrating Spheres              

 

  • Classical Integrating Sphere
  • Four ports
  • Post Mount

ISC integrating spheres come standard with ReflectraSpec coating (effective from 400nm-2500nm), four orthogonal ports (please specify orthogonal, 8 degree or custom configuration). Wall construction is cast aluminum (allows use of set screws).

Model Diameter Port Size
ISC-020 2" .5"
ISC-040 4" 1.0"
ISC-060 6" 1.5"
ISC-080 8" 2.0"

 

Port Plugs, Port Reducers, SMA and FC port adapters available. Please specify your requirements.

 

How to Select and Size an Integrating Sphere
In order to select the Spectral Products Integrating Sphere that is best suited for your application, several factors must be taken into consideration. The most important factors include the following:

Diameter/Source Ratio The diameter of the sphere should be at least 1.5 times the largest dimension of any device mounted within the sphere.

Surface-to-Port Area If ports cover more than 5% of the Integrating Sphere?s surface, the Integrating Sphere may not integrate properly. If port requirements are greater than 5% of the sphere, a larger sphere should be purchased.

The following formulas can determine port area and sphere surface area:

  • r = Port radius, D = Sphere Diameter
  • Port Area = pr^2
  • Sphere Surface Area = 4pD^2

Integrating Sphere Coatings The coating of a Spectral Products Integrating Sphere is a high efficiency diffuse reflector that delivers reliable integration and low throughput loss. The reflectance is high in order to minimize absorption loss from multiple reflections, yet it must not reflect light specularly.

Spectral Products Integrating Sphere Coatings offer reflectance efficiencies between 95 and 99%. A Lambertian Source is a perfect diffuse source. When a perfect diffuse reflector is illuminated with uniform intensity, it acts as a Lambertian Source. Spectral Products uses a proprietary ReflectraSpec coating, effective from 380 up to 2500 nm, to provide these state-of-the-art Lambertian properties.
