Zeicahdah a kau ngaimi F-theta lens ah a tthencheunak a cang

1. Off-Axis Aberrations cu Edge lei ah a karh

Laser ceunak nih optical axis in a hlat deuhdeuh tikah, a tthawng deuhmi off-axis optical region ah a lut.

Hi dirhmun ah hin, aa dangmi thil cheukhat cu zaangfah tein a biapi chin lengmang, cu hna cu:

• Field curvature

• Ei

• Astigmatism

A tthangchomi optical suaisamnak le tthatnak he hmanh ah, hi aa dangmi thil hna hi a hlei in zohfelnak angle ah tling tein hloh khawh an si lo, cu nih cun field tthennak ah riantuan ning a zorter.

2. Scan Angle ngan deuh nih F-theta tlukruannak kha a harter deuh

Hmun kau F-Theta Lens riantuannak hmunhma kau deuh hmuh khawhnak dingah a kau deuhmi zohnak angle a herh.

Sihmanhsehlaw, a ttha bikmi kha kilven F-theta pehtlaihnak (hmanthlak sannak cu scan angle he aa tluk) scan angle a karh tikah a har chin lengmang.

Mah nih direct in a hnorsuan khawh:

• Lo chung vialte ah aa khatmi hmun

• A kam chiahnak a dikthliar

• A dihlak in field linearity

3. Large Field Lens caah Optical Design Trade-offs

Scan tuahnak hmun ngan deuh (tahchunhnak ah, 300 × 300 mm asiloah a cunglei) hmuh khawhnak ding caah, optical designer pawl nih riantuannak thil tampi kha ralring tein an i tlukruan a hau:

• A kam hmunhma tthatnak

• Riantuannak hlatnak a herhmi

• Wavelength tthatternak (tahchunhnak ah, 1064 nm, 355 nm, 532 nm)

• Optical a harmi le sernak man

Hi i thlennak hna ruangah, a nganmi optical suaisamnak ah tthencheu riantuannak tlawmternak cu hrial khawh a si tawn lo.

4. Beam Incidence Angle ah theih khawhnak a karh

Scan field tthennak ah, ceunak cu a laifang he tahchunh tikah a tlawm deuhmi angle in lens chungah a lut.

Mah nih a hruaimi cu:

• Alignment palhnak ah a sang deuhmi hngalh khawhnak

• Thil sernak tuar khawhnak hmete in hnahnawhnak ngan deuh

• Mit hmuhnak tlawmpal aa tlak lo ruangah a chuakmi pialnak a karh

Cu ruangah, riantuannak hmun tthennak ah system aa dangmi hmete hmanh kha a lang deuh kho.

5. System-Level Thilri hna nih Edge riantuan ning zong a thlen

A tthencheunak cu F-theta lens lawng nih a chuahtermi a si lo ti hngalh a biapi.

Laser system taktak ahcun, a dihlak in riantuan ning zong hi a tanglei nih a hnorsuan:

• Galvo Scanner tahfung le tlukruannak

• Beam expander tthatnak le beam diameter aa tlakmi

• Luhtermi ceunak sining aa khatmi

• System tlukruannak a dikthliar

Hi thilri hna ah aa tlak lonak asiloah a fek lonak a um ahcun a kam thlennak kha a karhter chinchin khawh.

Zeitindah tuahsernak ah a tthencheunak kha zorter khawh a si

A nganmi hmunhma ah a tthencheunak cu hloh dih khawh a si lo nain, a dikmi optical le system suaisamnak thawngin ttha tein tlawmter khawh a si:

• A ttha bikmi thilri tampi F-theta lens suaisamnak hmang

• Laser hrampi he a dikmi beam expander aa tlak kha zohfel

• Galvo tahfung le linearity remhnak kha tthanchoter

• Wavelength-a hleiin remhmi lens suaisam kha thim

• System chung vialte ah a fekmi optical alignment kha kilven

A donghnak huapnak

A ttha ngaimi laser riantuannak ah—a bik in a nganmi hmelchunhnak, thlehnak le hrennak hmannak ah—a kam thlennak cu ralring tein tawlrel a herhmi a biapi mi hmuhnak lei zuamcawhnak a si.

A hrampi hngalhthiamnak nih engineer le system fonhtu hna kha a tanglei bantuk in tuah khawhnak a bawmh hna:

• A tlarimi thil tuah ning tthatnak

• A ttha deuhmi tthen a dikthliar

• A dihlak in system dirhmun ttha deuh

A donghnak ah, a dikmi F-theta lens thim le a dikmi system fonh khawhnak cu riantuannak hmun dihlak ah aa khatmi riantuan khawhnak hmuh khawhnak caah a biapi tukmi a si.
