Laser Mark Simulator

Features
Read full description

Laser Mark Simulator is a calibration aid for fiber laser color marking on stainless steel and titanium. It does not predict color — it computes the physics you can compute, narrows the search space, and keeps a record of what you actually observed. WHAT IT COMPUTES • Fluence F, spot overlap OL_x / OL_y, pulse count N and cumulative dose energy • Regime classification: oxidation, melting or ablation, from the fluence you set • MOPA and Q-switched behavior modeled separately — on Q-switched sources pulse width is derived from frequency, not entered • Effective average power capped by the rated frequency curve, so you see the drop below rating instead of discovering it on the part BEFORE YOU BURN A SPECIMEN • Small-character feasibility: stroke width against spot diameter and hatch lines per stroke, with a verdict and the reason behind it • Character heat distribution rendered from real glyph outlines and scanlines — relative energy, clearly labeled as such • Galvo delay starting values and an adjustment direction, not a claimed optimum • Throughput and heat build-up per part, with a recommended cycle interval CALIBRATION LOOP • Generate a primary test matrix over frequency and speed, with randomized marking order so heat accumulation shows up instead of hiding in a gradient • Record each cell with a 12-color label and a uniformity rating; only the index is marked on the specimen, parameters come from the CSV • Promote a promising cell into a secondary matrix at three power levels • Optional camera capture with an 18% gray patch for white balance, giving CIE Lab values and CIEDE2000 deltas against a reference cell RECIPES • Save a validated cell as a recipe; promotion to validated requires reproduction across two different material lots • Export EzCad pen parameters and matrix CSV • Convert a recipe to another lens focal length, with the metrics preserved and revalidation flagged • Changing a machine's source type invalidates its recipes rather than silently reinterpreting them SAFETY This app assists calibration. It provides no unattended-operation feature. Class 4 shielding, 1064 nm eyewear and fume extraction remain your responsibility, and every parameter must be verified by an actual test before production use. The calculation engine is free with no restrictions and carries no advertising. A one-time Pro purchase unlocks unlimited test matrices with EzCad export, cell photo color records and the recipe library.

Send yourself a thought — text, voice, photo, link, or file. MemoryBt turns scraps into to-dos, weekly reviews, and answers from your own records. Description: MemoryBt is a no-pressure memory app. Talk to yourself. Dump a rant. Drop a photo or a file. You do not need tags or folders. Every time you save, MemoryBt can turn that scrap into a to-do and a reminder for a specific day and time. Review draws a heatmap of your trail, and weekly and monthly recaps appear on their own. Ask answers from your personal records. Add material your way: type text, fetch a link, import files, pick photos for OCR, or scan pages. Check what to include, then organize. Speech and photo text run on your iPhone. AI organize, reviews, and Ask go through our server so the model key never sits in the app. The language in Settings only changes the app interface. MemoryBt supports 14 display languages. Default is English. Plans • Free: unlimited records, 8 AI uses per month • Plus: reminders on every record, 60 Ask uses per month • Pro: reminders on every record, 180 Ask uses per month Recording, voice, and photo text on your iPhone are free. Plus and Pro include instant organize and reviews. Ask uses the monthly Ask allowance. Payment is charged to your Apple ID. Manage or cancel in Settings → Apple ID → Subscriptions. Need help?

Verdict

The call

Laser Mark Simulator and MemoryBt are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
