Plan-Cleave Lensa Gambar pdf

Lensa optik minangka komponen optik transparan kanthi permukaan sudhut sing bisa nolak lan fokus cahya. Dheweke digunakake ing macem-macem sistem optik kanggo ngapusi sinar cahya, mbenerake sesanti, mbenerake obyek, lan mbentuk gambar. Lensa penting unsur-unsur penting ing kamera, teleskop, mikroskop, kacamata, proyektor, lan akeh piranti optik liyane.

Ana rong jinis lensa utama:

Lensa cembung (utawa konversi): Lensa iki luwih kandel ing tengah tinimbang ing sudhut, lan padha nggedhekake sinar cahya sing sejajar sing ngliwati dheweke menyang titik fokus ing sisih lensa line. Lensa Convex umume digunakake ing gelas gelas, kamera, lan kacamata kanggo mbenerake kedher.

Lensa concave (utawa diverging): Lensa iki luwih tipis ing tengah-tengah tinimbang ing sudhut, lan dheweke nyebabake sinar cahya sing padha lumebu liwat dheweke bakal teka saka titik fokus virtual ing sisih lensa sing padha. Lensa cekung asring digunakake kanggo mbenerake kanthi nearning.

Lensa dirancang adhedhasar fokus fokus, yaiku jarak saka lensa menyang titik fokus. Dawane fokus nemtokake tingkat lengkungan lengkah lan pambentukan gambar asil.

Sawetara istilah utama sing ana hubungane karo lensa optik kalebu:

Titik fokus: Titik ing ngendi sinar sinar cahya utawa katon beda sawise ngliwati lensa. Kanggo lensa Conveex, iku titik ing konversi sinar rambut paralel. Kanggo lensa cekung, iku titik saka sinar bedhah katon asale.

Dawane fokus: Jarak antarane lensa lan titik fokus. Iki minangka parameter penting sing nemtokake kekuwatan lensa lan ukuran gambar sing dibentuk.

Apenture: Dhiameter lensa sing ngidini lampu liwat. Aperture sing luwih gedhe ngidini luwih entheng kanggo ngliwati gambar sing luwih cerah.

Sumbu optik: Garis tengah sing ngliwati tengah lensa kanthi serphaces.

Kekuwatan lensa: Diukur ing diopter (d), kekuwatan lensa nuduhake kemampuan hiburan lensa. Lensa Convex duwe kekuwatan positif, nalika lensa cekung duwe kekuwatan negatif.

Lensa optik wis nggawe revolusi macem-macem lapangan, saka astronomiomy kanggo ilmiah medis, kanthi ngidini kita mirsani obyek sing adoh, masalah visi sing bener, lan nindakake imaging lan pangukuran sing tepat. Dheweke terus main peran penting kanggo nambah teknologi lan eksplorasi ilmiah.
