An electronic imaging apparatus includes a connecting section connected to an optical apparatus; an optical element having a preset transmittance with respect to light in a preset wavelength region, incident from the optical apparatus; and an electronic image sensor receiving the light transmitted through the optical element. An insulating layer is formed over the semiconductor wafer. Further, the slide is preferably positioned on the platform so that the platform provides a resting and staging area for the slide. Other embodiments are also described herein. An alicyclic allyl ester compound for plastic lenses, which can be obtained by a simple and easy production process and which can endure a long-term storage, is produced using the monomer, and a plastic lens is obtained using the compound.
