The Tunable KiloArc™ Illuminator 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.

Optical Shopper

Optical Choppers

If you would like to convert the continuous illumination of the Tunable PowerArc™ Illuminator into a pulsed light source then we have an optical chopper that can do the job. It can be used on a stand alone basis after the output from the monochromator. To learn more click here. Light Source, Monochromator and Optical Chopper
Sample Compartment

Sample Compartment

If you would like to couple your Tunable PowerArc™ Illuminator into a sample compartment, then we have an ideal solution. The OBB QuadraCentric sample compartment is an excellent unit that has various sample handling capabilities. The illuminator is f/# matched with the collection optics of the sample compartment for optimum throughput. You can then have up to three other input or output optical channels to or from the central sample holder. So you could create a right angle fluorometer or scatter system or a straight through absorbance spectrometer with the appropriate detection components. For each optical channel in the sample compartment there is also a filter holder for wavelength selection. To learn more click here. Light Source, Monochromator and Sample Compartment


Other Accessories

Collimating Lenses

If you need a collimated optical beam, then a collimating lens can be employed for the diverging beam after the light focal point. Be sure to match the collimating lens for your beam diameter requirements and for the f/# of the OBB light source you are considering. OBB offers a number of collimating lenses to choose from. Also if you need a uniform collimated beam of light be sure to consider an optical diffuser.

Optical Diffuser

An optical diffuser is necessary when uniform illumination over a targeted area is required.

Second Entrance or Exit Port

A second entrance to attach for example a second light source or a second exit can be added to the monochromator. It includes a flipping mirror for selecting desired exit or entrance as well as a slit assembly. If you desire both two exits and two entrances for the monochromator you need two of these accessories. Please note that if you select the optional computer controlled shutter, it is positioned inside the monochromator at the entrance port, so selecting this option precludes the use of a flipping mirror on the entrance port of the monochromator.

Programmable Computer Control

An optional computer control accessory is available. It includes a stepper motor assembly, an MD-2000 USB motor controller interface box and a LabVIEW* driver for computer control of the monochromator wavelength with LabVIEW software from National Instruments.

A very simple software package is also provided by OBB to remotely select the wavelength and control the shutter. Requires Windows 2000 or Windows XP operating system.
