View our latest version of this instrument, the LS-160.

Ranked in the higher DIN quality class B range, the LS-110 provides users with the most advanced light measuring technology available anywhere. This spot luminance meter is small and compact, light and easy to hold, and runs off a 9 volt battery, making it fully portable.

Features of this unit include an optical system with single lens reflex (SLR) technology that will give you accurate targeting capabilities while being able to see at all times the specific measuring area in the viewfinder  even when measurements are being taken at very short distances. Extremely small areas can be measured, even down to 0.4mm in diameter. With these and other advanced functions, even those using the device for the first time will achieve highly accurate measurement results.

The clear LCD screen shows the values of luminance measurements, and the values are also visible in the viewfinder. This means measuring tasks do not require moving the instrument from the eye yet still affording precise control of the object being measured. When measuring particularly strong light sources, comfort and safety are assured with the LS-110 s neutral density filter on the eyepiece. In all measurement operations, the device s pistol grip provides for a solid, secure hold.

With a range beginning at 0.001cd/m2, this instrument can measure surfaces that are extremely dark. Through color-correction and calibration functions, you re able to choose a standard luminance, and then the instrument automatically corrects when variances are spotted in specified sources of light. Users also can set measurement values to luminance ratio, instantaneous luminance and peak luminance. It s easy to connect the LS-110 to a personal computer, enabling it to send and receive various data.
