Figure G1.1 The holes in LVL02 can be used to measure the height of a beam larger than the hole. Click the photo to see an enlarged image with a zoom of the beam on the blade.
- Precision Machined Head and Bubble Level Ensure Squareness to 0.001°
- 12" Etched Stainless Steel Blade with 3 Different Inch Graduations: 8, 16, and 32 Marks per Inch
- Through Holes Every 1/4" and 1/8" Provide Easy Marking Access
- Heavy-Duty Machined Square Head
- Self-Aligning Drawbolt
- Hardened Scriber Included in Back of Head
The LVL02 Combination Square is a precision instrument with better sensitivity than similar instruments used in carpentry. Sensitivity is the measure of how large of a tilt is needed for the bubble to move, while accuracy is how close to true level the device measures. The stainless steel blade is marked with two scales on each side and is removable. One side is marked with 1/8" markings with 1/4" hole spacing and 1/16" markings with 1/8" hole spacing. On the other side, the ruler is marked with 1/16" markings with 1/4" hole spacing and 1/32" markings with 1/8" hole spacing. Also included with the combination square is a hardened scriber which is conveniently stored in the back of the head for ready access.
The holes in LVL02 can also be used to measure the height of a beam by aligning the square such that the beam passes through one of the holes. The height of the beam can be measured by determining which hole the beam passes through as shown in Figure G1.1.

Figure G2.1 The LVL03 Circular Bullseye Level is ideal for checking the level of optical tables.
- 37 minutes per 2 mm Sensitivity
- Made of Durable Acrylic
- Measures Level in XY Plane
- 30 mm Outer Diameter
The LVL03 Circular Bullseye Level is well suited for determining level position in the XY plane. It features an outer diameter of 30 mm and is made of durable acrylic. A clear liquid and white backing make it easy to visualize level by centering the bubble within the black central Ø8.8 mm ring. This level can be used in the lab to measure and set the alignment of optomechanical mounts, breadboards, and optical tables, as shown in Figure G2.1.
