The sensors on dedicated digital cameras are of higher quality than those found on digital SLRs. There are several types of dedicated cameras optimized for different applications. For example, cameras for black and white (monochrome) work lack a Bayer mask, which increases the sensor's spatial resolving power and sensitivity over color cameras. Additionally, cameras for monochrome work can be equipped with electronic coolers (Peltier devices) to reduce thermal noise. Such cameras are the preferred choice for low-light work that requires detecting fluorescent dyes.
