A variety of interchangeable accessories to enable application specific customization

Labsphere’s Integrating Sphere Accessories give users the ability to customize integrating spheres and systems to their specific measurement requirements. The interchangeable accessories are easily attached to port frames and matched to the integrating sphere wall reflectance value to ensure measurements accuracy.

Accessories allow users to create a uniform source or light measurement application with Labsphere’s General Purpose Integrating Spheres, or modify Labsphere’s Light Measurement and Uniform Source Systems to change or enhance functionality.


Labsphere’s Integrating Sphere Accessories offer one-stop shop for all of your application needs. The sturdy port frame design on Labsphere’s integrating spheres allow users to quickly mount accessories to the integrating sphere with the quick twist of a set screw.

Labsphere’s dedicated calibration lab provides a variety of NIST-traceable calibration options for systems that include accessories for specific application requirements.

Sphere Base Sphere Base

In a variety of sizes, Sphere Bases attach to a sphere post or post holder to allow the sphere to be freestanding.

$160 to $220
Sphere Post Sphere Post

Mounting posts are available in various lengths, with either English (1/4-20) or Metric (M6) threads, Posts slide into the sleeve of an optional base or post holder, which provides adjustable sphere height.

$25 - $30
Post Holder Post Holder

$50 to $55
Port Frame Reducer Port Frame Reducer

Mounting onto a port frame, a Port Frame Reducer effectively reduces that port frame to specified size. It serves as the
interface that permits accessories designed for a specific port size to be mounted on larger port frames.

$196 to $300
Port Plug Port Plug

Mounting on to a port frame, a Port Plug replaces the open port with a cap that matches either the reflectance of the sphere wall
or the open port.

$175 to $400
Port Reducer Port Reducer

Mounting onto a port frame, a Port Reducer reduces the clear aperture of that port frame.

$210 to $290
Detector Spacer/Filter Holder Detector Spacer/Filter Holder

Attachement to a port on an integrating sphere that allows for a detector or filter to be mounted to the sphere.  Available in flat black coating with apertures ranging from 0.125 -inch to 0.62 -inch.

$210
Filter Holder Filter Holder

Filters can be used for a variety of applications. They can modify the spectrum of light entering into the integrating
sphere, when mounted in front of a light source. They can enable light to be measured at a specific wavelength band,
when mounted in front of a detector port. And they can attenuate the signal level to avoid detector saturation, when
mounted in front of a detector port. 0.5, 1.0 and 2.0 inch versions are available.

$230 - $830
Sample Holder for RTC-060 Sample Holder for RTC-060

Allows samples to be held in the center of Labsphere’s RTC-060-SF Reflectance/Transmittance Sphere

$1,670 to $3,350
Powder Sample Holder Powder Sample Holder

Sample Holders are designed to hold reflectance and transmittance samples. Sample Holders mount onto a Port
Frame or Port Frame Reducer. The sample holder may be disassembled such that only the mounting plate remains to
accommodate large samples. Sample Holders are available in Spectraflect® or Infragold® coatings.

$475 to $535
Post Converter Post Converter

Converts a 1/4-20 Mounting thread to an M6 Mounting Thread for mounting abilities to an optical bench.
