Rancang Bangun Alat Penentu Panjang Fokus Pada Lensa Bikonveks Menggunakan Sensor Temt6000 Dan Motor Stepper

Abstract: Abstrak  Penelitian ini bertujuan untuk merancang instrumen pengukuran panjang fokus lensa bikonveks secara otomatis. Dengan menerapkan sifat lensa bikonveks dimana berkas-berkas sinar  yang paralel terhadap sumbu lensa akan dibiaskan dan berpotongan pada titik fokus. Titik fokus lensa ditentukan menggunakan sensor TEMT6000 dan panjang fokusnya diukur meggunakan motor stepper. Sinar dari dua buah laser dioda yang dipasang sejajar terhadap sumbu lensa akan berpotongan pada titik fokus sehingga intensitas … Show more

“…In manufacturing Meyer rod coating tools, a drive system must move the Meyer rod. In this drive system, the main component is an Arduino-based NEMA-17 stepper motor that will be controlled by a microcontroller depending on the input from the keyboard [23]. The motor is a driving component assisted by a TB6560 drive and a 12 V power supply.…”
