An information reading apparatus comprises a laser diode, a mirror having a planar emission mirror unit for reflecting a laser beam emitted from the laser diode towards a target optical pattern and a concave condensing mirror unit, formed integral with the emission mirror unit, for condensing a reflection beam from the optical pattern in a predetermined direction, a photodetector, situated in such a position as not to interrupt the reflection beam from the optical pattern, for receiving the condensed reflection beam and converting the same to an electric signal, and a mirror driving apparatus for reflecting the laser beam from the scan mirror in a reciprocal rotational operation by an attractive force of a permanent magnet and a coil and a restoring force of a resilient body clamped by dampers on both sides, and reciprocally scanning the beam over a bar code within a predetermined range.

Device for optically reading out information by use of laser beam

A cover slip for use in a microscope, which is employed for a water-immersed objective lens, is made of a transparent material with a refractive index, the difference between the refractive index of the transparent material and that of water being 0.02 or less.
