cal-SPOT401 Calibrated Spot Photometer
The cal-SPOT 401 is a calibrated precision spot photometer designed for user-friendly operation and accurate brightness measurements. It features a large LCD display with metric units, a calibration seal for authenticity, and an 'ON' and 'HOLD' button for easy operation. The device offers a wide viewing field with zero magnification, allowing comfortable use with both eyes open.
Key features include a NIST calibration certificate, no magnification, a 1-degree measuring spot, single-button operation, autorange from 0.1 to 400,000 cd/m2, auto power off, and a high stability silicon photodiode sensor with human eye response correction. It comes with a carrying case for convenience.
The cal-SPOT 401 measures luminance with a range of 0.1 to 400,000 cd/m2 and a measuring field of 1 degree. It has a viewing field of 12 degrees and operates without magnification. The working distance ranges from 1 yard to infinity. The sensor is a silicon photodiode with a photopic filter, and the spectral response follows the CIE photopic curve. The device maintains an accuracy of ±5% and operates within a temperature range of 32° to 130°F (0° to 55°C), with storage temperatures from -4° to 160°F (-20° to 70°C). Dimensions are 7.5” x 2.0” x 3.6”, weighing 22oz.
The cal-SPOT 401 is suitable for various applications, including road illumination studies, setting instrument controls, evaluating endoscopic instruments and other fiber optic light sources, psychological studies, greenhouse control, CRT measurements, and vision studies.
The cal-SPOT 401 is available for $2250, complete with instructions, battery, carrying case, and calibration certificate. It is certified to comply with standards traceable to the National Institute of Standards & Technology (NIST) and the National Research Council (NRC).
