Advantages compared to the VH Series

• Provides excellent resolution.
• Relatively inexpensive.
• Enables special observations. (Polarizing microscope, phase contrast microscope,
  differential interference microscope, fluorescence microscope, etc.)

Disadvantages compared to the VH Series

• The depth of field is shallow. (The focus range is narrow.)
• Illumination may be directed unevenly to the target; illumination setup conditions are not reproducible.
• Does not provide all-in-one configuration. (The system is difficult to use because the body, monitor and other units are all separate pieces of equipment.)
• Various functions are not available (such as measurement, depth composition, 3-D display and image-processing functions).
• To observe a large target, the target must first be processed. (Targets held in the hand cannot be observed.)
• A high-range zoom lens is not available. (It is difficult to use.)
• Requires a troublesome printing procedure. The printed image is different from the one observed visually.
• Has poor compatibility with personal computers. (It is difficult to transfer data to a PC.)
• Quickly creates eye strain in the user. The user needs to be well experienced in observation with both eyes.
• Several people cannot observe a target simultaneously. (They cannot hold a discussion about the target.)
