Optical Level

An optical level, also known as an auto level, is a surveying instrument that is used to determine the height and distance of different points on the land surface. It employs a telescope and a spirit level to provide accurate measurements. It is widely used in construction, civil engineering, and surveying projects. To use an optical level, first, the instrument is set up on a tripod and leveled using the built-in spirit level. Then, the telescope is aligned with a target and the height is read from a graduated scale on the instrument.

Buying Tips for Optical Levels and Auto Levels: A Guide to Choosing the Right Instrument for Your Construction Project

When it comes to construction projects, having accurate and reliable measurements is essential. That's where optical levels and auto levels come in. These tools allow for precise measurements of vertical and horizontal planes, making them essential for a variety of construction tasks. In this article, we will explore what an optical level is, how it works, how to use it, and some tips on buying one.

​

What is an Optical Level?

​

An optical level, also known as a dumpy level, is a precision instrument used for measuring vertical and horizontal planes. It consists of a telescope mounted on a tripod, which allows for precise measurements of the angle of inclination or elevation. The telescope is equipped with a spirit level, which helps to ensure that the instrument is level and accurate.

​

How Does an Optical Level Work?

​

The optical level works on the principle of a level line of sight. The instrument is set up on a tripod and leveled using the spirit level. The telescope is then pointed at a target, such as a staff or a leveling rod, which is positioned at a known height. The height of the target can then be determined by reading the scale on the leveling rod through the telescope. By taking multiple readings at different points, the level of the ground can be determined, and contours can be established.

​

How to Use an Optical Level?

​

Using an optical level requires some practice and skill, but with some basic knowledge, it can be mastered quickly. Here are some steps to follow:

​

  1. Set up the tripod: The tripod should be set up on a stable and level surface.

  2. Level the instrument: The instrument should be leveled using the spirit level on the telescope. Adjust the tripod legs to ensure that the instrument is level.

  3. Align the telescope: The telescope should be aligned with the target. Use the fine-tuning knobs to adjust the telescope until the target is in focus.

  4. Take a reading: Read the height of the target from the leveling rod through the telescope. Repeat this process at several points to determine the level of the ground.

  5. Record the readings: Record the readings on a surveying notebook or data collector.

Tips on Buying an Optical Level or Auto Level

​

When buying an optical level or auto level, there are several things to consider:

​

  1. Magnification: The magnification of the instrument will determine how far it can see and how accurate the readings will be. Higher magnification levels are better for longer distances and greater accuracy.

  2. Range: The range of the instrument will determine how far it can measure. Make sure the range is sufficient for your needs.

  3. Accuracy: The accuracy of the instrument is crucial. Look for instruments that have a high level of accuracy, as this will ensure 

  4. more reliable and precise measurements.

  5. Durability: Construction sites can be tough on equipment, so it's important to choose an instrument that is durable and can withstand harsh conditions.

  6. Brand reputation: Choose a brand with a good reputation in the construction industry. Brands such as Bosch, Leica, and Topcon are well-known for producing quality instruments.

  7. Accessories: Look for instruments that come with useful accessories, such as tripods, leveling rods, and carrying cases.

  8. Budget: Optical levels and auto levels can vary in price, so it's important to have a budget in mind. Consider the features you need and choose an instrument that fits within your budget.

  9. In conclusion, an optical level or auto level is an essential tool for construction projects that require precise measurements of vertical and horizontal planes. Bosch offers a range of reliable and accurate instruments, such as the Bosch GOL 26 D Professional Optical Level and the Bosch GOL 26 G Professional Auto Level. When buying an optical level or auto level, consider factors such as magnification, range, accuracy, durability, brand reputation, accessories, and budget. With these tips in mind, you can choose the best instrument for your needs and ensure accurate and reliable measurements on your construction projects.
