Yesterday, I received two laser pointers from Laserlands. A friend of mine unintentionally shined the laser to my right eyes mistakenly. I blinked immediately and I had after images for 1 minute. I got hit from a distance less than 1 meter. I measured the power of the two pointers and it shows...
Case Material Aluminum + Copper for diode casing
Dimensions: L = 16 cm, D=14 mm
Laser shape: dot
Switch mechanism: press ON- release OFF ( Like normal laser presenter)
Lens: do not know, you cant access the lens without taking the laser apart.
Shipping: It depends on the service you choose...
A true < 5mW 450nm laser from laserlands, costs $ 18, Free Shipping is available but I used DHL :D , It's worth buying. The beam is visible in the dark. Laser power is verified and tested on my university LPM and on my LPM. there was a slight variation of 0.6 mW. The laser is safe for...
You said young child he probably shined the laser in his eye for a good amount of time, a normal person should survive < 5mW laser, 250ms is enough for a normal person to blink. A young child shouldn't be allowed to have a laser pointer. A 5mW can damage your eye only if you resist blinking...
You will blink before damage occurs as long as it is < 5mW so, it is eye safe. I got a direct hit from that laser, I only had after images for a minute and everything returned back to normal. The fact that it is bright and 3mW makes this laser safe as you will blink before damage occurs. It is...
I received the laser today, I measured the output power, it outputs 3mW, which is eye safe.
The pen is heavy and has no warring sticker.
The dot is visible during the day and the dot is orange
at first, I thought it's 20mW or more but it ends up 3mW which is 100 % eye safe...
Thanks, That will be my next purchase :D, I will buy the 520nm laser from laserbtb, they offer good prices and low power output < 5mW. I will ask Kevin to measure the power before shipping it like he did with my < 5mW violet laser.
Hi, I was checking my green laser. It was 4.9 mW in the winter. Now it's varies output 7mW and maximum of 8mW. I added an IR filter and found that it returned back to 4.9mW so, probably there is IR leakage of approximately 3 to 4mW. I'm not sure if that makes the pointer danger or not. 4mW of...
I bought a cheap Chinese safety goggle to use it with moderate power lasers i.e 20mw laser. I tested the glasses on my LPM and I cannot believe what I saw.
First claimed Specifications
Protection wavelength range: 190nm-540nm
Protection features: all-round absorption :crackup:
Yes, it has many applications. Probably a good idea in fact I' m planing to add a 405nm laser to detect black objects ; I'm not sure if purple laser will be completely absorbed by black objects or not; hopefully it will work but 520nm is probably the best solution but it is quite expensive at...
I'm planing to buy a 635nm laser pointer and I'm not sure which one is better.
AtlasNova 635nm Red Laser Pointer
Libra Series 635 nm Red Laser Pointer
Hi,, This is a review for a laser proximity sensor. It can be used for different applications like: smart robots. The sensor has a weakness it does not detect black objects since black objects does not reflect the laser (it absorbs most of the red laser). The sensor uses 3 wires 2 for powering...
Hope you believe me I win a bid on ebay. The laser costs me $ 27 including USPS priority express. It arrives in 2 days in the original box with everything including the original battery no wear no sign of use. The seller have young children and was afraid of the laser getting to their hands :D...
The Laser comes in a plastic box without batteries for easily custom clearance.
Laser model is LP 405nm - 5B
Maximum Power is 5mW
My LPM reading shows 4.03mW and 4.78mW maximum power ( pretty close to Kevin measurement:D)
Beam Color violet
It come in a great metal box
The laser is class 3R < 5mW.
Both the beam and the dot are clear at night
I measured the laser on my LPM to make sure it is as advertised. The power was fluctuating between 4.74 and 5mW
Laser class: Class 3R
Laser type: Diode-pumped solid...
Hi, The seller told me that this is a low power laser and no need to wear safety glasses. I found that it is approximately 13mW. Is it considered a low power ?. Do I need to wear a safety glasses at these power or just common sense ?
Here is seller message
The laser you have bought is...
Sorry, for miss understanding your question. I was confused about the laser beam and laser dot. You cannot see the beam except when it's too dark, you could see a very thin beam when viewing the laser directly. It is not good for viewing the beam, if you care about the beam then a 100mW will do...
