The HLMS-200P is an easy-to-use, precision photometric instrument designed for use in the field, laboratory or on the production floor.
The HLMS-200P instrument measures luminous flux from sources such as LED
The HLMS-200P is compact, lightweight, and rugged with a handle-grip enclosure and a built-in microprocessor that performs several functions at the touch of a button.
Data is instantly displayed on an easy-to-read 4-digit front panel LCD display. Simple push button controls are easily accessible and clearly labelled on the front panel. The instrument is powered by a 9V battery and is calibrated to display lumens.
A full line of precision, configurable digital light meters (radiometers/photometers) with a comprehensive selection of light detectors (light sensors) for measuring a wide array of visible, UV, and infrared light sources such as lamps, LEDs, and lasers are available from Warsash Scientific.
All light meter systems are fully calibrated with NIST traceability. Annual re-calibration services through International Light Technologies are also available.Send Enquiry
Wavelength Range: 200-1700nm
The StellarNet model spectrometers are great tools for low cost, routine analysis of all types of light. From measuring the irradiance of standard light bulbs to measuring the exact colour coordinates of the yellow in a traffic light. They are used worldwide to routinely analyse light.
These instruments are calibrated to measure the spectral irradiance in units of watts per meter squared over the wavelength range in nanometres provided by the selected spectrometer model. Warsash Scientific offer Radiometer systems in the 200-1700nm range. Calibrated spectroradiometers can be used to measure absolute intensity, xy chromaticity (CIE 1931), purity, correlated colour temperature, and dominant wavelength.Send Enquiry
LED manufacturers and luminaire designers require a quick, portable device for complete spectral flux analysis. Reliable measurements of small LEDs, fibre outputs, and other small sources has usually meant compromising on accuracy or speed. As the leader in the field, Labsphere has designed a sphere-based portable solution including self-absorption correction that is both reliable and affordable.
Labsphere's series of illumia® Light Measurement Systems are the optimal choice for spectral flux measurement solutions. Featuring a wide range of high-end spectrometers, MtrX-SPEC software®, Labsphere light measurement spheres and lamp standards, Illumia Light Measurement Systems are configurable for all applications.
Labsphere's Illumia® Pro Light Measurement Systems allow users to quickly, accurately, and simultaneously measure the optical and thermal characteristics of various LEDs and arrays.
Typical quantities for LED
The most common method for measuring the total luminous flux of any source included OLED
For directional applications, LED intensity and spatial distribution are the most important parameters. For intensity measurements, a precision entrance port into a near cosine sphere detector is configured for Condition A or B measurements where the device is located 316mm or 100m respectively away from the entrance port of the sphere intensity head. The head is coupled with a spectrometer with application-based software calibrated for spectral intensity responsivity.
