The Dark Reader blue light transilluminators can be used for viewing a wide range of fluorescent samples including SYBR Green, GelStar, GelGreen, SYPRO Ruby, ProQ Diamond, fluorescein and various GFPs.
There currently is 4 different sized transilluminators available :
An amber screen that fits exactly over the blue surface is included with each transilluminator. The amber screen absorbs the blue excitation light, after it has illuminated the sample, thereby allowing the user(s) to clearly see the fluorescence. The amber screen can also be used as a camera filter.
All Dark Reader transilluminators are also provided with a free pair of viewing glasses with exactly the same optical properties as the screen. The glasses are a key accessory for cutting bands out of gels.

It is a commonly held misconception that for a fluorophore to work with the Dark Reader it must have an excitation maximum between 420 - 500 nm and an emission maximum above ~ 520 nm. While these are useful guidelines, it should be emphasized that the DR can also be effectively used to detect fluorophores that have maxima well outside outside these ranges.
