Commarker Omni 내부 1: UV 레이저가 새겨진 정밀도에 깊은 다이빙

그만큼 컴마커 옴니 1 is not your average desktop 레이저 조각사. 펄스로 355 NM UV 레이저, sub-25 nanosecond pulse widths, and swappable F-Theta lenses, it enters a new class of photonic precision. But what makes it different—and why would anyone choose this over a higher-powered 60W infrared fiber system?

Let’s take a look under the hood, at the beam, and deep into the glass.

UV vs IR: Why Wavelengths Matter

Infrared lasers (like fiber and MOPA) dominate in general purpose engraving: 궤조, 컬러 마킹, deep cutting. But UV lasers, with their shorter wavelength, open doors to materials that are transparent to IR—like plastics, 목재, 유리, or PCBs.

UV’s shorter wavelength:

• Enables 광화학 절제 rather than thermal burning
• Creates extremely small spot sizes for high DPI and clean micro-cuts
• Allows for sub-surface engraving in transparent materials

결과: Less heat, more control.

Optical Precision – The Truth About Spot Sizes

옴니 1 includes two F-Theta lenses:

• 70×70 mm lens – Shorter focal length, smaller spot size
• 150×150 mm lens – Larger working area, but lower resolution

While theory suggests sub-40μm spot sizes, real-world measurements yielded:

• ~53 μm with the large lens
• ~40 μm with the small lens (with fine-tuning)

For comparison: CO₂ lasers typically operate in the 100–200 μm range.

Pulse Widths and Beam Quality – Why It Matters

옴니 1 allows users to dial in 빈도 (kHz) 그리고 펄스 지속 시간 (ns):

• Best results (roundest beam profile): 30 kHz / 12 ns
• Too short or too long disrupts beam symmetry (TEM00 degrades)

Changing pulse parameters dramatically affects:

• Beam shape
• Focus accuracy
• Energy delivery per impulse

This matters especially for glass work, PCB micromachining, 그리고 surface coatings.

Application Highlights

Here’s where this UV laser shines:

재료	결과
플라스틱	Crisp white marks, no melting or charring
목재	Clean, micro-thin cuts with minimal burn
유리	Can embed 3D models 내부에 the glass
PCB	Micro-etch traces with <100μm precision
직물	Surface bleaching or engraving without damage
규소 / ICs	Selective removal of epoxy molding

메모: Always use proper dust extraction. UV glass cutting releases hazardous micro-particles.

Inside the Omni 1 – A Technical Teardown

Control and Optics:

• JCZ controller card
• True Galvo mirrors
• Motorized Z-axis (on newer models)
• 소프트웨어: 라이트번 (limited for automation), or open-source Balor

Laser Module:

• DPSS laser with Nd:YAG crystal
• Q-switch driver for nanosecond-scale gating
• Tripled frequency via harmonic generation to 355 nm
• Thermoelectric cooling throughout
• Accessible pump diode (replaceable)

⚠️ Tip: Beam parameters affect thermal lensing in crystals—keep pulse energy consistent.
