Abstract
According to various embodiments of the present invention, an optical capture system is provided. In one embodiment, a micro-scale optical capturing system is provided with low divergence (approximately 1°) of the incident light and low acceptance angle (<8°) of the captured light. According to embodiments, a micro-scale optical capturing system is provided with a large number of collimated high-power white LEDs as light sources, between 60 and 100 units, for example, and may be positioned at distances of about 650 mm from the sample. In one embodiment, a digital camera using 50 mm focal objective with a 25 mm length extension tube captures images of the sample. This provides a working distance of approximately 100 mm and at the same time maintains ×0.5 magnification for microscale captures, with an image size of 4×4 microns per pixel.
