Laser Power Meter, Sanwa, Mfr#: LP10

This instrument is a pocket-sized laser power meter featuring outstanding design and portability.The Sanwa LP10 is a Digital Laser Power Meter that features a 4039 count LCD display with an analog bar graph. This is used in checking and maintenance of the optical power levels of equipment using laser light.Using 633 nm of a He-Ne laser as the reference wavelength, this instrument enables direct reading of the optical power of visible-range laser light from a visible laser source – pointer, DVD players optical pickup, etc. The power of other wavelengths can also be measured by converting the reading according to the spectral sensitivity characteristic table typical values.The light sensor in this device is a silicon photodiode light sensor surface diameter 9 mm with a diffusion sheet. It can measure wavelengths within the 400 nm to 1100 nm range. The cleverly designed cover folds flat in back of the unit when in use, and protects the unit when closed.
