## Abstract

A sample preparation method includes: irradiating a first region of a sample with light at a time t1; irradiating a second region different from the first region with the light at a time t2 after the time t1; and fixing the sample at a time t3 after the time t2. A sample preparing apparatus includes: a light radiating unit that irradiates a first region of a sample with light at time t1 and irradiates a second region different from the first region with the light at a time t2 after the time t1; and a fixing unit that fixes the sample at a time t3 after the time t2.

## Claims

### Claim 1

A sample preparing apparatus comprising:
a light radiating unit, including a lens, that irradiates a first region of a sample with light at a time t1 and irradiates a second region different from the first region with light at a time t2 after the time t1;
a fixing unit, including a valve, that fixes the sample at a time t3 after the time t2; and
a computer that automatically sets the first region and the second region in response to a first input by a user indicating a number of regions to be irradiated with light, and automatically sets the time t2 and the time t3 in response to a second input by the user indicating an irradiation interval of time.

### Claim 2

A sample preparing apparatus comprising:
a light radiating unit, including a lens, that performs:
irradiating a first region of a sample and a second region different from the first region with light at a time t1;
irradiating the first region with light at a time t2 after the time t1; and
irradiating the second region with light at a time t3 after the time t2; and
a fixing unit, including a valve, that fixes a composition of the sample at a time t4 after the time t3.

### Claim 3

A sample preparing apparatus comprising:
a light radiating unit, including a lens, that irradiates a first region of a sample and a second region different from the first region with light for mutually different lengths of time after simultaneously starting an irradiation of light; and
a fixing unit, including a valve, that fixes a composition of the sample after the irradiation of light.

### Claim 4

A sample preparing apparatus comprising:
a display; and
a controller configured to cause the display to display a setting screen that allows a setting of an order of performing:
irradiating a first region of a sample with light;
irradiating a second region different from the first region with light; and
fixing a composition of the sample.

### Claim 5 (depends on 4)

The sample preparing apparatus according to claim 4, wherein
on the setting screen, a duration of an irradiation of the first region of the sample with light and a duration of an irradiation of the second region of the sample with light can further be set.

### Claim 6 (depends on 4)

The sample preparing apparatus according to claim 4, further comprising:
a light radiating unit, including a lens, that irradiates a plurality of regions of the sample with light; and
a fixing unit, including a valve, that fixes a composition of the sample, wherein
the controller controls the light radiating unit and the fixing unit based on information set on the setting screen.

### Claim 7

A sample preparing apparatus comprising:
a display; and
a controller configured to cause the display to display a setting screen that allows a setting of:
a time at which a first region of a sample is irradiated with light;
a time at which a second region different from the first region is irradiated with light; and
a time at which a composition of the sample is fixed.

### Claim 8 (depends on 7)

The sample preparing apparatus according to claim 7, wherein
on the setting screen, the first region and the second region can further be set.

### Claim 9

A sample preparing apparatus comprising:
a display; and
a controller configured to cause the display to display a setting screen that allows a setting of:
a time t1 at which a first region of a sample is irradiated with light;
a time t2 at which a second region different from the first region is irradiated with light after the time t1; and
a time t3 at which a composition of the sample is fixed after the time t2.
