Note: a separate camera filter is not needed for the photography or imaging of fluorescent samples using any of our transilluminators or GelHead! All these units are equipped with an amber screen that effectively functions as a camera filter.
 
The filters offered by Clare Chemical have exactly the same optical properties as the amber screen. They have been introduced for those researchers who prefer to operate their Dark Reader transilluminators without the amber screen. Substituting the screen with a camera filter can be helpful, for example, in humid climates where condensation tends to form more rapidly under the screen. Also, if you wish to photograph materials illuminated by the Hand Lamp or Spot Lamp, you will need a separate filter. In the case of the GelHead, the amber screen is an integral part of the electrophoresis apparatus and must be in place for the unit to function.
 
Attaching a filter to a digital camera usually involves additional accessories. For example, with most cameras, a 'lens adapter tube' is required. The tube screws to the body of the camera, over the lens. A filter can then be screwed onto the other end of the tube. In some cases, the thread size of the tube is 'non-standard' and so it is also necessary to purchase a 'step-up ring'. The ring is threaded at both ends: one end attaches to the tube and the other end will accept a standard-size filter. Tubes and rings are purchased from the camera supplier.
