3GENERAL INFORMATION

SpectraPen LM 510 is a handheld portable spectroradiometer that is ideal as a general-purpose instrument for research

and for agricultural applications. SpectraPen LM 510 measures in radiometric or photometric units the intensity of the light

irradiance and is calibrated for visible light in the range of 380 –780 nm for UVIS version and 640 –1,050 nm for NIR

version. SpectraPen is used for irradiance measurements, illuminance measurements and CIELAB chromaticity diagram

measurements. SpectraPen is especially useful for rapid measurements of spectral light quality, for monitoring of artificial

lighting and for quantification of light radiation.

The SpectraPen is powered by a built-in, rechargeable Li-Ion battery and does not require a PC or any other bulky accessory

for operation. The SpectraPen touch screen displays continuously the wavelength and intensity readings and their spectral

traces including correlated color temperature index. All recorded data are automatically stored in the internal memory of

the device. The SpectraPen includes a comprehensive software package (for a PC) comprising full system control, data

acquisition and data processing.

The built-in GPS module and splash-proof case are ideal for field use of the SpectraPen and make this device well suited

for wide scope of environmental, agricultural and ecological applications such as monitoring of artificial lighting used in

horticulture industry or light source testing.

Parameters measured by the SpectraPen:

Scope - quantitative light intensity at different wavelengths

•Irradiance spectrum [µW.cm-2.nm-1]

•Photon flux density spectrum [µmol.m-2.s-1.nm-1]

Light Meter - absolute light intensity at defined range of wavelengths of the electromagnetic spectrum

•Irradiance [W.m-2] in user defined range of the electromagnetic spectrum

•Photon flux density [µmol.m-2.s-1] in user defined range of the electromagnetic spectrum

•Illuminance [Lux] - total luminous flux incident on a surface, per unit area

•PAR [µmol.m-2.s-1]*

Chromaticity Diagram CIE1931 - quality of color space and color temperature of the light source

•CIE color coordinates*

•Correlated color temperature –for LED *

•Color rendering index

Users defined formulas in SpectraPen software

* Valid only for LM 510-UVIS version of SpectraPen LM 510

3.1 DEVICE DESCRIPTION

Cosine corrector

The optical sensor of the SpectraPen and the cosine corrector, is placed inside of the black box positioned on the front

panel which protects the optics from dirt or moisture. The sensor is covered with a teflon ring placed either on top

(horizontal position) or in front (vertical position) of the optical head depending on the device version.

Integration time of the detector is set automatically according to the ambient light intensity up to a maximum integration

time of ten seconds.

Each SpectraPen device is calibrated with the certified light source AvaLight - DH-BAL-CAL. Calibration certificate is

provided by the manufacturer for each device.

The sensor should be always dust and dirt free and protected when not in use, as any scratches on

the surface might interfere with measurements and results

Color touch screen display

The SpectraPen is operated via touch screen by using provided stylus. Instructions on how to operate the unit are provided

on page 16.

No sharp objects should be used when operating the SpectraPen via touch screen. It is

recommended to use provided stylus when making selections on the touch screen.

Connector for USB cable

USB connector on the device together with the USB cable provided, is used for re-charging the device battery and for

operation of the SpectraPen directly from a PC via the SpectraPen software (downloaded to PC).

Power button

Power button is the main Switch ON/OFF button.

5CARE AND MAINTENANCE

SpectraPen

•Never submerge the device in water!

•The device should not come in contact with any organic solvents, strong acids or bases.

•Keep the optical sensor cover clean and dry. If cleaning is needed, use soft, non-abrasive tissue.

•Do not use sharp objects for touch screen operation.

It is recommended to re-calibrate the device by the manufacturer every 2 years.

Li-ion battery

•Battery power lasts approximately 48 hours when the SpectraPen is operated continuously.

•Avoid fully discharging of the battery.

•Do not keep the battery at full charge for long periods of time. Allow for it to discharge.

•High temperatures shortens battery life.

•If the battery can no longer be charged, please contact PSI for replacement battery and installation

instructions.
