1.4 Outline of Measurement Principle
1.4 Outline of Measurement Principle


After taking measurement, the oscillator is not emitting
ultrasound waves.
The SP-100 is designed for pachymeter or corneal thickness measurement by
using ultrasound transducer, built in Pachymeter probe.
zSP-100 emits the ultrasound from the Pachymeter probe and the
probe also receives the ultrasound reflected by surface between
corneal posterior face and anterior chamber.
zSP-100 measures the period of time from emitting ultrasound to
receiving the same ultrasound, reflected by corneal posterior part.
Applying a calculation formula shown below, corneal thickness
can be calculated.
L= ———
Where, L: Corneal Thickness
V: Converted sound velocity
(Ultrasound Velocity through cornea)
T: Measured time (Ultrasound transmission
time between emitting and receiving)
zThis instrument is powered by rechargeable battery or AC power
adapter. Even when the battery power is running short, SP-100
can perform measurements, while charging the battery, by plug-
ging to AC power adapter.
zThis instrument is designed to take corneal thickness measure-
ment automatically, when the probe is applied to cornea properly.
zThis instrument is capable of sending and receiving patient infor-
mation and measurement data between the external equipment
through the serial communication port. (Additional cable must be
used, when using this function)

Connector of the Probe should be inserted in speci-
fied direction. Insert the connector as deep as it
sounds "click".
Insert the connector Ainto the connecting terminal B
marked "PROBE" on the front side of Main Unit.
b) Connection of AC Adapter
Insert the connector to the terminal completely
Insert AC adapter connector Ainto the connecting termi-
nal Bprovided on the right side of the Unit.

3.2.3 Optional components
Assembling of the Disposal Tip Pachymeter Probe and alternative Probe shapes
The Disposal Type Pachymeter Probe (supplied as
an optional component) consists of the inner probe,
case, fixed ring, and disposal tip.
The Probe can be changed in two alternative shapes:
(A) with 45 shape and (B) in straight shape, de-
pending on the application convenience.
<How to assemble>
1) Cover the inner probe Awith a pair of cases
Bto make the inner probe clipped in between
and fix it with the rubber rings C.
2) Apply a small amount of methylcellulose (such
as Dry Eye Gel) on the tip of the inner probe
A.

cause air bubbles inside of the tip.
<How to assemble the Probe in alternative shape>
1) Disassemble the disposal tip D, fixed ring C,
and the case Bin order.
2) Assemble the case Bto be changed and next
fix it with the rings C.
3) Next apply a small amount of methylcellulose
to the tip of the inner probe.
4) Then securely insert the disposal tip Dnot to
