by | Apr 7, 2023 | Blog

Borescopes and endoscopes are types of inspection cameras. Although there are many similarities between endoscopes and borescopes, there are some key differences. In this comprehensive guide, we’ll explain what borescopes and endoscopes are, explore the differences between the instruments and discuss their uses and applications and the benefits they offer.

What is a borescope?


A borescope is an inspection camera, which is inserted into an object to enable the operator to see the inside of the structure, engine, casting, or some other manufactured device. Borescopes are also used to explore environments to enable us to see areas we wouldn’t otherwise be able to view. Today, borescopes are often used remotely.

A borescope comprises a miniature camera, which is attached to a thin, flexible, semi-rigid, or rigid tube. Using a borescope provides access to hard-to-reach or poorly lit areas as well as the inside of structures. This visual inspection tool offers a range of benefits for organizations and individuals across multiple industries. Using a borescope facilitates the inspection of structures and environments, which are not visible or accessible to the naked eye.

Borescopes are used predominantly for industrial, manufacturing and aviation, and aerospace applications.

It is important to search for the word ‘borescope’ if you want more information. It is very common for people to search on sites like Google using terms like borascope, bora-scope, bore scope, bore-scope, or even bor-a-scope.

Types of borescopes

There are several types of borescopes. As technology has advanced and evolved, the range of instruments and applications has increased. Examples of types of borescopes include:

Video borescopes

A video borescope is one of the most common types of borescopes. Using a tiny camera, which is fitted to the top of the instrument, the borescope captures video footage, which can be viewed using a monitor or a computer screen. Video borescopes are also known as videoscopes. They work by transmitting light through the lens to the video camera. They can capture stills as well as video clips.

Flexible borescopes (fiberscope camera)’


Also known as fiberscope cameras, flexible borescopes comprise a flexible tube. They use optic glass fibers, rather than lenses, to transmit the image from the camera to the eyepiece. The flexibility of the tube allows for excellent coverage, and it can also enhance the quality and clarity of the image.

Rigid borescope


Rigid borescopes have a fixed, immobile rod. They utilize lenses to transmit high-resolution images. As the tube is rigid, this type of borescope has to be inserted into a specific structure or environment in a straight position. It cannot bend or flex but it is possible to see different views using mirrors and prisms. In most cases, the operator will use an eyepiece, rather than a camera, to view images. The rigid borescope is available in various lengths and prob diameters. The rigid borescope can also have a fixed angle of view. The most popular AOV for a rigid borescope is 0 or 90 degrees.

Semi-rigid borescope


Semi-rigid borescopes are not as flexible as fiberscope cameras but they use the same fiber optic technology to relay images. Their small diameter makes them an excellent choice for inspecting micro components and very small structures.

What is an endoscope?

An endoscope is a type of borescope camera, which is used most frequently within the medical and veterinary sectors. Endoscopes are inspection devices, which are employed predominantly to see inside the human body or the body of an animal. Every endoscope can be classed as a borescope, but not every borescope can be classified as a borescope.

Endoscopes have a very thin, flexible, long tube, which facilitates movement and provides access to areas that would otherwise be impossible to investigate or reach. An endoscope features a tiny camera, which is positioned by moving the cable, and an LED light source.

Endoscopes are used during procedures known as endoscopies. There are several types of endoscopies, which are conducted to gather information about specific parts of the body. An endoscopy may be recommended if an individual has symptoms that warrant further investigation, they are due to have treatment, or they have undergone treatment or recovered from a condition or injury. Endoscopies play an integral role in the diagnosis, treatment, and management of a wide range of illnesses and diseases.

Common types of endoscopies include:

  • Colonoscopy: used to explore the colon
  • Bronchoscopy: used to investigate the lungs and airways
  • Cystoscopy: used to look inside the bladder
  • Laryngoscopy: used to examine the larynx
  • Laparoscopy: used to investigate the abdomen and pelvic area

What are the differences between a borescope and an endoscope?

There are multiple similarities between a borescope and an endoscope, but there are important differences between the two instruments. These include:

1.   Diameter

An endoscope has a smaller diameter than a borescope. Endoscopes can be used to explore extremely narrow passageways and areas that are difficult to access. Some mini borescopes can be as small as .37mm in diameter.

2.   Flexibility

Borescopes come in many different forms and some are more flexible than others. Flexible borescopes enable enhanced maneuverability while rigid and semi-rigid borescopes are more limited. Endoscopes have a very long, thin, flexible cable, which enables the operator to move them around and navigate complex systems and pathways, usually inside the human body.

3.   Field of view

One advantage of using a borescope over an endoscope is the field of view. Endoscopes only offer a 90-degree field of view while borescopes provide a 120-degree field of view. It is possible to enhance the view when using an endoscope by adjusting the device.

4.   Application

One of the main differences between borescopes and endoscopes is the way they are used. Borescopes are employed across multiple industries while endoscopes are most commonly used by doctors and veterinarians. Borescopes are designed specifically for aerospace, manufacturing, and industrial applications. They may be used by mechanics, engineers, plumbers, aerospace and energy technicians, and automotive engineers, as well as law enforcement officers. Endoscopes can be used within other industries. Industrial endoscopes are used in automobile production and maintenance, but endoscopes are found much more commonly in healthcare and veterinary settings.

5.   Detail

Endoscopes are known for providing extremely detailed images. They offer a superior level of detail to borescopes, which is why they are used in the fields of medicine and veterinary care where risks are high and accuracy is vital.

6.   Cost

The cost of borescopes varies, according to the type of instrument and its intended function. As borescopes are much more versatile and they cater to a much wider range of industries and applications, they are usually less expensive than endoscopes. Endoscopes are medical-grade devices, which often have a relatively high cost. Amateurs, hobbyists, and small business owners can access low-end borescopes while endoscopes are only accessible to organizations that have the budget to buy specialist, cutting-edge equipment.

7.   Lighting

Borescope light tends to be brighter and more intense than endoscope light. Endoscopes require softer light because this provides better conditions for examining the internal structures and organs of the body. The intense light generated by borescopes increases visibility within structures and places where there is no natural light.

What are the pros and cons of borescopes and endoscopes?

Borescopes and endoscopes are capable of performing many of the same tasks. However, often, there is a clear winner in terms of which instrument is best suited to a specific job. There are pros and cons to using borescopes and endoscopes.
