A method for evaluating an evaluation target includes: an irradiation step of irradiating an evaluation plate, in which an evaluation target is held in a plurality of wells provided in the evaluation plate, with illumination light from a light source; an imaging step of imaging the evaluation plate while the evaluation plate is irradiated with the illumination light; and an evaluation step of evaluating the evaluation target based on an image of the evaluation plate obtained in the imaging step, in the imaging step, imaging of the whole of the evaluation plate is ended in less than 120 seconds from start of irradiation of the evaluation plate with the illumination light in the irradiation step, and irradiation with the illumination light is ended after end of imaging of the whole of the evaluation plate in the imaging step.

A spectroscopy instrument and method including a source of electromagnetic radiation, a controllable power source for energizing the source of electromagnetic radiation to direct the electromagnetic radiation to a sample for analysis by one or more spectrometers, and a temperature sensor. There is a controller, memory, and controller instrument warm-up instructions, stored in the memory. The instrument warm-up instructions are configured to read an output of the temperature sensor. If the temperature sensor output indicates an instrument temperature lower than a first setpoint, the power source is controlled to energize the source of electromagnetic radiation to heat the instrument. If the temperature sensor output indicates the instrument temperature is equal to or higher than a second setpoint, the power source is controlled to de-energize the source of electromagnetic radiation.
