摘要:
A fixed focus microscope objective lens designed for high magnification viewing of homogenous specimens. The fixed focus microscope objective comprises a last surface 16 which serves as a specimen mount and enables the device to operate in focus without the need for focus adjustors in the microscope system. The user can observe specimens by simply placing a sample of the specimen on the fixed focus objective lens surface 16. There is no need for preparing a microscope slide, focusing, or positioning the specimen. By eliminating focus and stage adjustors the microscope becomes both simpler to operate and less expensive to manufacture. A fixed focus microscope objective lens can be used by novice microscopists to obtain high quality images at high magnification for nominal cost, and can convert a common video camera into a high quality video microscope.
