Spyder 3 GigE User’s Manual 39 4.2 Optical Interface Illumination The amount and wavelengths of light required to capture useful images depend on the particular application. Factors include the nature, speed, and spectral characteristics of objects being imaged, exposure times, light source characteristics, environmental and acquisition system specifics, and more. DALSA’s Web site, 13Hhttp://vfm.dalsa.com/, provides an introduction to this potentially complicated issue. See “Radiometry and Photo Responsivity” and "Sensitivities in Photometric Units" in the CCD Technology Primer found under the Application Support link. It is often more important to consider exposure than illumination. The total amount of energy (which is related to the total number of photons reaching the sensor) is more important than the rate at which it arrives. For example, 5μJ/cm 2 can be achieved by exposing 5mW/cm 2 for 1ms just the same as exposing an intensity of 5W/cm 2 for 1μs. Light Sources Keep these guidelines in mind when setting up your light source: • LED light sources are relatively inexpensive, provide a uniform field, and longer life span compared to other light sources. However, they also require a camera with excellent sensitivity, such as the Spyder 3 GigE camera. • Halogen light sources generally provide very little blue relative to infrared light (IR). • Fiber-optic light distribution systems generally transmit very little blue relative to IR. • Some light sources age; over their life span they produce less light. This aging may not be uniform—a light source may produce progressively less light in some areas of the spectrum but not others. Filters CCD cameras are extremely responsive to infrared (IR) wavelengths of light. To prevent infrared from distorting the images you scan, use a “hot mirror” or IR cutoff filter that transmits visible wavelengths but does not transmit wavelengths over 750nm. Examples are the Schneider Optics B+W 489, which includes a mounting ring, the CORION LS- 750, which does not include a mounting ring, and the CORION HR-750 series hot mirror. Lens Modeling Any lens surrounded by air can be modeled for camera purposes using three primary points: the first and second principal points and the second focal point. The primary points for a lens should be available from the lens data sheet or from the lens manufacturer. Primed quantities denote characteristics of the image side of the lens. That is, h is the object height and h′ is the image height. DALSA 03-032-10158-06
