1 Look directly down the laser

Some people out of curiosity, trying to fix a fault or just out of sheer stupidity will look down a laser into the lens where the laser beam comes out. I don't care whether your finger is off the on button, you've taken the batteries out or if the guts of laser are spread all over your work bench, you NEVER look down a laser. You would never look down the barrel of a rifle and in the same way you should never look down the laser.

Most eye injuries with portable lasers have occurred when some one was looking down their laser thinking it was safe. A classic case was when a laser enthusiast looked down their laser when cleaning the lens only to realize too late that they forgot to take the batteries out. That person now has a permanent blind spot in their eye.

2 Point the laser at aircraft

This looks like a very obvious not to do with a laser but judging from the amount of people out there pointing lasers at aircraft, it is not obvious enough.

Apart from the safety and hazard issues involved, pointing lasers at aircraft is a federal offence in just about every country. So if you want to end up in federal penitentiary breaking rocks for the next 10 to 20 years, please go ahead and be my guest.

If there is one thing that sensible laser enthusiasts hate, it is people who point lasers at aircraft. Not only is it dangerous and incredibly stupid, it is also responsible for over regulating portable lasers to a point where the hobby may not have a legal future.

3 Point the laser at people

Another obvious "not to do with a laser" that too many people out there don't seem to understand. High power lasers are dangerous to your eyes so if you point a laser at some one, there is a chance you will injure their eyes. It is that simple.

Sure you might just be pointing the 500mW laser pointer that can light cigars at their hand, the back of their head or on the bridge of their nose where every one knows is safe. What happens though if they move, your hand slips, some one bumps you or any one the many things that can go wrong do go wrong? What happens is in that one split second you are responsible for that person losing partial to complete vision in that eye.

4 Use the wrong equipment or method to clean the lens

The most common cause for damage to laser pointers and even laser modules (apart from being dropped) is people clean the lens incorrectly. The lens in lasers is a precise and delicate optics that is easily damaged so great care needs to be taken when cleaning them. There are a lot of methods for cleaning lens ranging from tissues and t-shirts to microfiber and lens pens.

The only completely safe methods of cleaning laser lens is to gently blow compressed air on the lens and to use professional optics cleaning tools such as lens pens. If you do use some material such as cotton buds, make sure you also use a fluid such as lens cleaning fluid. Cleaning the lens when they are dry will just cause dust on the lens to scratch them.

5 Modify lasers

Modifying a laser is when you use one of several methods to increase the power to the laser diode so the laser beam has more power. All lasers, whether they are laser pointers or laser modules can be modified and it sounds like a very cheap way to get a high power laser.

The problem with modifying lasers is that lasers are not designed to handle the increased power levels and modifying them will normally damage or destroy the lasers in a matter of minutes. If you don't mind ruining your laser or you are interesting in modifying your laser as an experiment, go ahead. If on the other hand you've spent several hundred hard earned dollars to buy your laser, leave it as it is.

The Light Emitting Diode story

1907: Henry Joseph Round discovers the physical effect of electroluminescence. But as he is working on a new radio direction finding method for marine vessels this discovery is initially forgotten.

1962: The first red luminescence diode, type GaAsP, is launched. 1971: LED in other colors are available: green, orange, yellow. There are continual improvements in the output and effectiveness of all LEDs.

1993: Highly efficient InGaN diodes emitting in the blue and green spectrum are demonstrated. The conditions for creating white light are met.

1995: The first LED with white light created by luminescence conversion is launched.

For more than 30 years, LED have been used in various industrial applications from switch cabinets to measuring instruments, in consumer products such as HiFi- equipment, telephones or personal computers, in traffic signal installations for road and railway or in indoor and outdoor automotive lighting. automotive lighting.

In the last few years the efficacy of colored LED increased up to amazing 100 lm/W and more depending on the color and driving conditions. A trend which will proceed in the future.

As today's white LED reach efficacies up to 40-100 lm/W (efficiency depends on color temperature and color rendering) - they are more and more used in general lighting. In emergency lighting as well as decorative lighting, they are already established in implementation area. Today, also applications such as illuminated advertising benefit from the advantages of LED, particularly by using colored LED-modules.

Basic principles of LED (Light Emitting Diodes)

• LED consists of several layers of semiconducting material
• When an LED is operated with DC voltage light is generated in the active layer
• The generated light is radiated directly or by reflections -In contrast to lamps, which emit a continuous spectrum, an LED emits light in a certain color
• The color of the light depends on the used material
• Two systems of material (AllnGaP and InGaN) are used in order to produce LED with a high luminance in all colors from blue to red and also in white (luminescence conversion). Therefore different voltages are necessary in order to operate the diode in conducting direction.

The production of white light

To produce white light, the light of blue LEDs is passed through yellow phosphors. The composition of the phosphor determines the light color.
The Chip Level Coating (CLC) process developed and patented by OSRAM ensures a degree of homogenity in the light produced that other processes cannot achieve. By selecting appropriate white LEDs, it is possible to offer LED systems with the same light colors as fluorescent lamps (Warm White, Neutral White and Daylight).

Innovative LEDs offer a number of technological advantages

• Low energy consumption
• Extremely long life
• Very low early failure rate
• Smallest dimensions
• Shock and vibration resistant
• No ultra-violet or infrared radiation
• Low wattage
• Almost no heat generation
• Directed light - Lambertian emitter with beam angle 120°
• High color saturation

any body have any computer junk?

anybody have any computer junk they dont want anymore?
like a 16xdvd burner?
or a 200mw laser diode?
or like a
650nm 5mW laser module.3.2V to with lens 650 nm OEM?
im working on a very expensive project and would really appreciate
the help
or if anyone has any computer junk just tell me and you can ship it to me! i would pay for the shipping cost and everything!
thing of me like a junkyard collector person or something like that.

i have almost any thing on that list!
