OBB Optical Chopper

Digital Optical Chopper Accessories


The OC-5000 optical chopper is one of many inter-connectable optical components. Hence the name of our company, Optical Building Blocks Corporation. These Optical Building Blocks can be ordered together to form a complete subassembly or they can be subsequently added to one another. In fact there are enough OBB components to choose from to build your own complete optical system for various spectroscopy requirements.

Light Source

Arc Lamps

OBB has an excellent selection of high intensity arc lamp systems. The OC-5000 optical chopper can be used on a stand-alone basis to pulse the otherwise continuous output of one of these light sources. We have a light shield adapter tube that can hold the optical chopper to physically connect the chopper to the arc lamp housing and create a portable pulsed illuminator. Inside the light shield you can also add an optional IR filter to remove the heat component of the. To learn more about our arc lamp systems, click here.

PMT Detectors

OBB Corporation has a selection of detectors that can be coupled to the sample compartment, including PMT housings (cooled and non-cooled) and NIR InGaAs detectors. These detectors can be used in conjunction with the OC-5000 optical chopper and a lock-in amplifier to reduce signal noise. To learn more about our detectors, click here.
