3 High - Performance Kit Options

Select the ideal kit based on your project requirements:

Kit No. Included Components Unique Advantages
Kit 1 - K40 laser head
- USA - made ZnSe CVD D12FL25.4 focus lens (12mm diameter, 25.4mm focal length)
- D20 silicon reflection mirror (20mm diameter, 97% reflectivity) 		Precision Cutting: The short focal length of the D12FL25.4 lens enables ultra - fine cutting, perfect for intricate designs on thin materials such as paper, acrylic sheets, and thin leather.
Kit 2 - K40 laser head
- USA - made ZnSe CVD D12FL50.8 focus lens (12mm diameter, 50.8mm focal length)
- D20 silicon reflection mirror 		Deep Engraving Mastery: With a longer focal length, this lens excels at deep engraving on thicker materials like hardwood, 5mm+ acrylic, and dense leather, creating rich, three - dimensional textures.
Kit 3 - K40 laser head
- USA - made ZnSe CVD D20FL50.8 focus lens (20mm diameter, 50.8mm focal length)
- D20 silicon reflection mirror 		Versatile Performance: The larger 20mm diameter lens reduces beam divergence, offering balanced performance for a wide range of materials. Ideal for mixed - material projects, medium - depth cutting, and high - volume production.
