To convert a digital camera to Full Spectrum involves removing the UV/IR Cut Filter [ Hot Mirror ] that covers the CMOS sensor, this allows all wavelengths of light to hit the sensor. However with no filtration the image will be a bit soft as no lens can focus UV, Visible and Infra Red light to the same point, but by simply adding a filter to the front of the lens in use, will allow photos to be taken in whatever type of light is desired. So adding an IR Pass filter will block UV and visible light and only allow IR through to the sensor and the results will be exactly the same as an IR Conversion with the same wavelength of filter but with the advantage that you can simply change the filter's wavelength or to pass UV or some other effect for Astro work.
To convert a digital camera to Infra Red involves removing the UV/IR Cut Filter [ Hot Mirror ] that covers the CMOS sensor, then a IR Passing [Visible Blocking ] filter is added where the UV/IR Cut Filter was removed. This filter is permanent and the camera will only be able to "see" the IR light that the filter passes.
Why convert a camera to Full Spectrum or Infrared, Can't I just give more Exposure?
Why convert a camera to Full Spectrum or Infrared, well the photos below are taken with a 21mm lens and a Hoya R72. The first on an unconverted camera is taken at 1/20th at f/2.8 with the camera set to a whopping 65535 iso!!, the second at the same time, with a Full Spectrum Camera, was taken at 1/200th at f/5.6 with 100 iso. By removing the UV/IR Cut filter in a Full Spectrum or IR camera conversion, the camera is gaining a massive 15-16 stops of IR light!!.
1st Sept 2020 - The Shop Pages have now been restored and sales can resume. However towards the end of each month I will have to assess the sales level to keep below the VAT threshold. This may mean sales may be paused again towards the end of each month.
Full Spectrum Conversion for Astrophotography
The image below of the Orion Nebula is taken with a Full Spectrum Converted Sony A7R with a normal 600mm camera lens [Slightly Cropped]. The image colour, especially the red H-Alpha intensity is increased due to the UV/IR Cut filter removal as part of the Full Spectrum conversion.

To the naked eye this area [In Orion's Sword] looks like a slightly fuzzy star, but with the extra exposure [12x 60s exposure = 12mins in total] the camera can see the above, which surprisingly [To me anyway] is roughly the size of a full moon.
19/08/2021 - I have conducted a few trial sales to EU countries in the last few weeks, which have all gone very smoothly, so I am now accepting orders from the EU again. There will almost certainly be an import tax payable by you on entry to the EU at your local VAT rate, this may also add a bit to the delivery time. Please contact me first before sending a camera for conversion, so we can discuss Import/Export Customs Arrangements.
PayPal have recently decided that they won't refund their 3-5% Transaction Fee when sales are cancelled or refunded, so unfortunately I will have to follow suit in the case of some refunded sales. If the sale has to be refunded due to no fault on my behalf I will deduct PayPal's fees from any refund. This will even apply to sales where the delivery address has to be changed as PayPal offer no other way of changing the delivery address after the transaction is placed.
