Ocean Optics has added an accessory option for its Jaz modular sensing system, enhancing performance in standoff light-measurement applications. The Jaz adjustable laser pointer (ALP) is a tool for making accurate spot measurements of large-area projection screens, flat panel displays, media walls and other samples where precise focus within large areas of light emission are necessary.

The laser pointer focuses the Jaz’s collection optics to a precise spot within the sample being measured. The addition of the ALP module to the Jaz stack, along with a separately available Gershun Tube Kit, controls the field of view of the spectrometer from 1° to 28°. A low-power laser pointer pinpoints the sampling area from a distance of 2 to 14 m, as factory calibrated. Greater distances may be achieved with readjustment. Four Torx adjustment screws allow vertical and horizontal control of the laser beam direction. The laser pointer is powered separately from three AAA batteries and includes a power switch with a red LED “on” indicator.

The Jaz modular sensing platform is a family of stackable components that share common electronics and communications. Its CCD-array miniature spectrometer can be optimized for a variety of measurements by choosing grating and slit options. An onboard microprocessor with a built-in display eliminates the need for a PC. Its mix and match accessories, including additional spectrometer channels, battery packs, Ethernet connectivity, software packages, light sources and now the ALP, make the Jaz customizable for virtually any measurement application.
