Technician in Precision Optics (TPO) Certification Exam Preparation

These flashcards cover key terms and concepts related to the Technician in Precision Optics (TPO) Certification Exam, including laser safety, optical properties, and optical instruments.

Laser Safety Officer (LSO)

Responsible for overseeing laser safety protocols in facilities using Class IIIb lasers.

Infrared Spectrum

Begins at wavelengths above 700 nm.

Primary hazard of lasers

Optical radiation exposure.

Chemical spill protocol in optics lab

Evacuate the area and alert others.

Heavy metal waste disposal

Requires special hazardous waste collection.

Ultraviolet light hazard

Can cause skin and eye damage.

Eye protection for lasers

Use laser safety goggles specific to the laser wavelength.

Maintenance of optical equipment

Secure loose clothing and disconnect power sources before performing maintenance.

Control of dust in optics lab

Effective with proper ventilation.

Class of lasers safe under most circumstances

Class I lasers.

Purpose of laser interlocks

To prevent accidental exposure to the laser beam.

Primary hazard of methanol

High flammability.

Collimator's primary use

To make light rays parallel.

Biconvex lens focus

Brings parallel rays of light to a focus at the focal point.

Coherence in light

Refers to the phase relationship between waves.

Characteristics of coherent light source

The waves are in phase and outputs a single wavelength.

Monochromatic light

Light of a single wavelength.

Effect of anti-reflective coatings

Increase light transmission through lenses.

Birefringence

Occurs when light of opposite polarizations refract differently in a crystal.

Energy relation to wavelength

Shorter wavelength means higher energy.

Light behavior entering a denser medium

Slows down and bends toward the normal.
