Thumbs up Review of the 980P-100-BL 980nm Laser Pen

980P-100-BL 980nm Laser Pen, retail $13.30
Manufactured by (Unknown)
Last updated 05-16-15




The 980P-100-BL 980nm Laser Pen (hereinafter, probably just called a, "laser pen" or simply a, "laser") is a rather unique product when it comes to portable lasers. It outputs a primary beam of laser radiation at a measured power output of 86mW at a wavelength of ~980nm in the NIR (near-infrared). 980nm is invisible to humans but is easily viewed with most digital cameras and night vision equipment.

However, what spurred this laser purchase is that it generates a very weak (est. ~80pW {picowatts} secondary emission at approx. 490nm in the cyan region of the spectrum!

SIZE



To get the laser to turn on, first be certain that there are a pair of AAA cells installed. If there aren't, then install them (see directly below), and THEN you can go irradiate some glow powder to watch it deplete more than areas that are not irradiated or something.

Aim the laser well-away from your face first. Press & hold down the button on the barrel for as long as you want or need the rather invisible laser spot, and release pressure on the button to neutralise the laser.



To change the batteries in this NIR laser, unscrew the laser near the center, and set the front section aside.

Tip the two used AAA cells out of the barrel and into your hand, and dispose of, recycle, or recharge them as you see fit.

Insert two new AAA cells into the barrel, nipple-end (+) positive first. This is the opposite of how batteries are installed in most flashlights, so please pay attention to polarity here.

Screw the front portion of the tube back on, and be done with it.

Unable to measure current use due to how this laser was constructed.



Power output tops out at 86mW on a LaserBee 2.5W USB Laser Power Meter w/Thermopile.

Beam terminus photograph on the active surface of a Pocket View-ItŪ IR Detector Card.
This photochemical detector uses anti-Stokes passive wavelength conversion to allow you to see NIR radiation.


Photograph "looking down the barrel" as it were to show a very low-powered (est. 80pW) laser line at ~490nm.

This weak emission is visible as a cyan (blue-green) dot on a white surface in a darkened area; it also has significantly higher divergence than the primary 980nm beam does. The beam terminus spot increases in size quite rapidly as the laser is moved away from the surface; the cyan dot apppears to double in diameter from the laser aperture being point blank to being pulled approx. 1 foot (0.3048 meters) distance.


Spectrographic analysis of the 490nm line.
The NIR filter from the Lasever LSR473-ML-100 120mW 473nm DPSS Blue Laser was used here.



Spectrographic analysis of the 490nm line; spectrometer's response narrowed to a band between 475nm and 495nm to pinpoint emission, which is 490nm.

The raw spectrometer data (tab-delimited that can be loaded into Excel) is at http://ledmuseum.candlepower.us/47/980.txt

Multiple beam cross-sectional analyses would normally appear here, but the ProMetric System
that I use for that test was destroyed by lightning in late-July 2013.


In leiu of beam cross-sectional analyses, I present to you this photo taken with the aid of a diverging lens, that helps you to see its beam configuration.

Default Re: Review of the 980P-100-BL 980nm Laser Pen

I got one of these, and I'll just add my findings here, rather than make a new thread.

Draws 135-155mA, and stays in regulation down to 2.2V which makes NiMH rechargeables perfect for this pointer.

Power output is very stable at ~85mW. I did see a glimpse of the cyan at one point, but didn't attempt any measurements on it.

Since the whole system only dissipates ~1/3W of heat, temperature rise is negligible, and can therefore be left on indefinitely without worry of overheating.

+1 for the spectro confirmation of the extra line(s)!

This little laser is a marvel indeed!

Can you spectro the 980nm line or is it outside the range of your spectrometer?

It's also be interesting to spectro other units to see if they all have the same exact lines or if they drift with the mains line. If they do drift it's probably enough to affect the color perception.

Thank you for the +rep!

Unfortunately, the longest wavelength my Ocean Opticas USB2000 spectrometer can resolve is 874nm, so the 980nm output as the primary laser line is too deep into the IR for me to capture.

The Ocean Optics PC2000-ISA spectrometer I used to have could have done this (I believe that it had a long-end of 1000nm), but I had to sell it in order to forestall an eviction in September 2009.
