The most common lens options are 1.5, 2.0, 3.0 and 4.0 inch. These measurements refer to the focal length (see diagram), required for each lens to be perfectly in focus. For example, a 1.5” lens needs to be precisely 1.5” above the face of the material to be properly focused. The main factors differentiating each lens, is spot size and depth of focus. The smaller lens, the smaller the focal length and spot size.

How do laser focus lenses work? Lasers use an intense beam of light to cut, engrave or etch directly onto the surface of a variety of materials. For instance, a focus lens in a Co2 laser cutter/engraver converges the laser beam to create a focus point where the laser is cutting or engraving the material. This point is at the sharpest convergence of the beam, and is commonly referred to as the ‘spot size’. Several factors affect this spot size, which will ultimately determine the outcome of your project.

– Best overall, a good compromise of focus sharpness and depth of etching– Can cut materials of relative thickness, with appropriate laser power input– Mostly used for engraving

The larger the lens, the larger the spot size and depth of focus, increasing the cutting capability. Larger lenses are recommended for cutting thick materials and cutting at increased speeds. However, the larger the lens the more you will be sacrificing engraving resolution. The spot size also affects beam energy, which is why a larger lens requires a higher wattage laser.

– Largest depth of focus– Best used for cutting thick materials or engraving materials with curvature– Very large spot size requires high power lasers.

STEM Day on November 8 is an annual opportunity for educators to celebrate and inspire a love of science, technology, engineering, and mathematics in their students. This day recognizes the growing importance of STEM in preparing students for a rapidly changing world and encourages hands-on learning experiences that can spark […]...

For woodworking, engineering, and other hands-on STEM activities in schools, having the right tools is essential. Air compressors are invaluable in powering tools such as nail guns, paint sprayers, and airbrushes, helping students complete projects quickly and efficiently. However, not all compressors are created equal. The new Forza Oil-Free Compressors […]...

A smaller lens allows for finer resolution when engraving. However, smaller lenses have a reduced depth of focus, causing decreased cutting capacity and are only recommended for cutting thin materials.

This article will explain these differences and aims to give you a deeper understanding on which lens is the most appropriate to use.

Most laser cutter/engraver systems will come standard with a 2 inch lens as this gives the best overall performance, with a balance of good engraving resolution and cutting capability. See overview below.

It's National Recycling Week this November 11-15! This week offers educators a prime opportunity to teach students how small actions—like recycling properly or repurposing materials—can have a powerful environmental impact. This week, let’s focus on practical ways to give resources a second life, reduce the need for new resources, and […]...
