Frequently Asked Questions
What is an integrating sphere used for?
An integrating sphere measures total optical power independent of beam shape or direction, making it ideal for LEDs, laser diodes, and fiber outputs.
Why use an integrating sphere instead of a standard photodiode?
A photodiode measures only incident light at its surface, while an integrating sphere collects light from all directions, providing accurate total power measurement.
What coatings are used inside the gold integrating spheres?
Gold coatings are highly reflective diffuse materials optimized for the infrared.
What sizes of integrating spheres are available?
Integrating spheres are available in many diameters depending on application and power level. These sizes include 20mm, 25mm, 50mm, 65mm, 100mm 115mm, and 200mm diameter.
Can high-power lasers damage the sphere?
The maximum optical power depends on the size of the sphere and detector used. Limits for your configuration will be outlined in the documentation provided.
Could a part be provided for your integrating spheres to limit input apertures for varying sizes?
We can provide customised solutions to fit your requirements.
Do you offer recalibrations for your Integrating Spheres?
Yes, we do. Periodic calibration is recommended to maintain measurement accuracy.
Can you measure larger ranges than what is listed in your brochure?
Multiple photodetectors can be connected to the sphere at the same time allowing for great flexibility in what each sphere can measure.
How do I align a beam into an integrating sphere?
Alignment is generally not critical since the sphere diffuses incoming light.
Can integrating spheres measure LEDs?
They are widely used for LED power and luminous flux measurements.
Can multiple ports be used simultaneously?
Integrating spheres often have multiple ports for detectors, sources, and monitoring equipment.
Are Artifex devices suitable for laboratory research?
Yes, they are designed for both research and industrial testing environments.
Do the instruments support computer control?
Artifex instruments support PC control for automation and data acquisition.
What software is used to control the devices?
Custom control software or compatible measurement platforms can be used.
Can multiple devices be integrated into a single test setup?
Users may combine devices such as laser drivers, power meters, and integrating spheres.
Do Artifex devices support automated testing systems?
All Artifex devices can be integrated into automated optical test stations. Instruments with software come with a full software development kit (SDK) including our graphical user interface (GUI), source code and typically a LabView VI and / or Python driver.
What maintenance is required?
Typical maintenance includes:
– periodic calibration
– connector inspection
– optical surface cleaning
Where can I get technical support?
Technical support is available through Artifex Engineering.
