LR-55 - LED Receptor
|
|
|
|
|
Designed to measure discrete LED's, the accessory accepts 0.125" (3.18 mm) diameter
and 0.25" (6.36 mm) diameter LED's. Calibrated for radiant intensity (µw *
sr-1) and luminous intensity (millicandela) with an 8° acceptance
angle. Replaces the MS-55 during use. Consult factory for alternate LED diameters.

|
LR-127 - CIE 127 - LED Analyzer
|
|
|
|
This patented optical accessory is designed to test discrete LED's for compliance
to CIE 127. Tests both conditions A (far) and B (near) of the CIE recommendation.
Calibrated for luminous intensity (millicandelas). Both conditions can be tested
with the flip of a lever from 'A' to 'B'. No need to change tubes or even remove
the LED between tests. Accepts T1 (3 mm) and T1.75 (5 mm) packages. Replaces the
MS-75 during use. Consult factory for alternate LED packages.
