Laser Flashlight

Understanding Photonics and How it Applies to You

Photonics, optoelectronics, spectroscopy, and other scientific terms sound like some words a scientist made up (well technically they did), but they are actually descriptions of a very specialized field of particle physics called Photonics.

In laymens terms, Photonics is the study of light and optics. It’s a very simple definition, but the field is so massive and broad that it’s applications are used in just about everything. Stop and think for a moment – how much of your daily life is affected by lights, heat, and physics? If you go through your daily routine, you’ll actually find that almost everything you do is affected by these.

Here’s a few obvious examples of what the Photonics field is used for – every light bulb, flashlight, and device that emits any kind of light. This can also be digital signal displays such as computer monitors, cell phones displays, and HD television. This are the most obvious applications of photonics as they’re in your life every single day.

But what about the more discrete applications? How about telescopes, they uses lenses to refrect light to enable you to see great distances. What else uses lenses? Your glasses sure do.

There’s also biomedical imaging – such as xrays and ultrasound – those were made possible because of the photonics industry. And thanks to it, there are people doing research on how to use lasers and lights to deal with serious medical illness (i.e. There are several Universities doing research on using lasers to get rid of cancer and alzheimers disease, etc).

Digital signals are sent thanks to photonics technology breakthroughs, such as fiber optics – that fastest known median for data communication. Imagine where the world would be without things like satellite transmission – there’d be no cellular phones, no live pictures from other parts of the world, and no way to predict the weather all around the world. Again, these are just a few of the applications that are available today because of this research.

Just about every military uses photonics-based technology as well. Did you know that almost all US aircraft are equipped with multple laser-based technologies? They’re in place to communicate with their superiors, target their weapons, and defend themselves – there’s a laser that is designed to destroy incomming missiles that has been mounted on several aircraft.

What Sides Are There?

There’s several different groups of people who are part of the photonics industry, and you’re in at least one of them:

Researchers – Most universities provide grants and resources to expand the field of photonics. They realize how massive and important the field is that it’s quite uncommon to find a university that isn’t putting research into it.

Manufacturers – These large companies will take the research from the universities and turn it into products (such as glasses, telescopes, light bulbs, etc).

Customers – That’s us, the people who buy the goods that are a direct result from photonics research. Think about this – how many light bulbs do you go through every year? How often do you get new glasses or contact lenses? Those products are on the market today thanks to the research that is done.

If you are interested in learning more about photonics, there are numerous books available as well as online publications. Be warned though, it’s a fascinating field and you might get hooked!

Can you take the Laser and Flashlight off of the Gamo Varmint Hunter Scope?

I’m thinking about buying one, and I need to know because I only need the flashlight for night hunting and i don’t need the laser at all, and I want it off.
Also,
how accurate is this gun?
What pellets does it ‘like’?
I’ve heard from many different people that the scope that comes with it is low quality, what scope should I get for a second scope, that’s maybe about $100 or less?

And one more question, what other gun could I get that shoots lead pellets around 1000fps (not too much more please) that has a synthetic stock, and is very accurate, for hunting where the exact vital spot has to be hit every single time?

Thank you
Actually, for the last question, it doesn’t have to be a synthetic stock.

Also, what do you think about the Gamo Hunter Sport, is it accurate and powerful enough to take out big bunnies, and accurate enough to do so every single shot?

thank you again.

rws 34 is a better quality gun and more accurate in my opinion! adventuresinairguns.com has them for $190synthetic or $195wood. they also sell scopes! make sure that the scope is airgun rated. spring guns vibrate really hard and can damage most scopes. ive killed many bunnies with airguns and i think 22 is better for rabbits and squirrels, but 177 will work with a temple shoot! rws super domes, jsb exacts, beeman fts and crossman premiers are good pellets worth trying, but each gun may like something different. yes you can take laser or light off and gamo hunter is good enough. 1000fps is just advertising, but it will get 900fps which is not bad! dont use the pba ammo, it will damage the gun in the long run! hope this helps
