Frequently Asked Questions

What resolution does the KD-5100 achieve?

Using two precisely matched sensors per channel, the KD-5100 resolves positional change down to a nanometer, with long-term stability of 5×10⁻⁶ inches/month or better.

What applications is the KD-5100 designed for?

Night vision systems, precision telescope positioning, fast steering mirrors (FSM) for space and airborne use, and image stabilization — anywhere small size, stability, and nanometer resolution matter.

Is there a commercial (non-MIL-SPEC) version?

Yes — the DIT-5200 is a commercial equivalent for applications where MIL-SPEC qualification, size, weight, and power consumption are not critical.
