Infrared Light Sensor

I am a camera setup, where a camera is used with a telephoto lens of 35mm. In the process of the lens of the webcam stock has been deleted. This webcam actions had a lens with a coating which blocked infrared light. Without this the colors are distorted. What I need is a cheap way to block the infrared light, but without distorting the image. Photo stores sell filters that effect .. but they cost as much as the webcam $ 100 or more.

CCDs are quite sensitive as far as 0.95, or 1 micron, while our eyes lose their sensitivity of 0.7 microns.

It is a common problem when there are many "off the shelf" solutions.

The CC1 or CC2 Xnite filters Maxmax would do $ 39 for versions 25 mm in diameter. http://www.maxmax.com/aXRay25mmFilters.a ...

For about the same price, Edmund has a better selection of shapes and sizes. http://www.edmundoptics.com/onlinecatalo ...

Find someone with glass cutting skills to get the shape and size you want. You can also buy a webcam broke out at the best price on craigslist or eBay and get this filter. Whatever the difficulties in the cam, the filter is the last thing that will fail!

If you want to go cheap, you can try to blow a few dollars on these: http://scientificsonline.com/product.asp ... that might do the trick blue but do not count on it .

In fairness to the community, not everyone sees the issues to be aware of the transmission curves and how the perception of color, but I suspect that most who do will also be able to find sources of filter. Flag abuse

What did you with the objective of stock? Did you throw it??

You just need to buy another filter infrared camera.

A hundred dollars for a filter looks like a lot of money. I can not offer a filter on top of my head, but there are several manufacturers of filters that can be useful. Try Kodak Wratten filters - camera stores data. Also, filters could do theater, it was made by Lee, Rosco and GAM, which are sold by NPLT Seattle (www.pnta.com).
