Modular integrating sphere concept
The modular integrating sphere concept from Gigahertz-Optik offers a high flexibility level when it comes to individual configuration of integrating spheres. In addition to the various components such as port frames, baffles and sockets that can be directly mounted onto the integrating sphere, port adapters with different functions are also offered.
Variable apertures for intensity regulation
When high stability of the luminous flux and emission spectrum are required, halogen lamps and semiconductor light sources such as LEDs must be operated at constant electric power. The best way to regulate the intensity levels is therefore to use adjustable apertures to allow for the required effective luminous flux in the sphere through fine-tuning of the port openings.
LS-OK30-VA variable aperture for the LS-OK30 module light source
The LS-OK30-VA will be mounted between the LS-OK30 module light source and the UMPF-LSOK30 port frame. The two-plate design together with the high resolution manual drive ensures a high resolution over the entire usable range of operation. The apertures plate coating is well suited for the high temperatures from the halogen lamps.
Variable aperture for a wide dynamic range
The LS-OK30-VA can be used with the LS-OK30 filter exchange holder. This combination makes it possible to extend the intensity adjustment dynamic range using holes-pattern attenuation filter.
