Lensa Plano-Concave Gambar PDF

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

Ana rong jinis lensa utama:

Lensa cembung (utawa konvergen).: Lensa iki luwih kenthel ing tengah tinimbang ing pinggiran, lan nggabungake sinar cahya paralel sing ngliwati dheweke menyang titik fokus ing sisih ngelawan lensa. Lensa cembung biasane digunakake ing kaca pembesar, kamera, lan kaca mata kanggo mbenerake rabun adoh.

Lensa cekung (utawa diverging).: Lensa iki luwih tipis ing tengah tinimbang ing pinggiran, lan njalari sinar cahya paralel sing ngliwati dheweke dadi beda kaya-kaya teka saka titik fokus virtual ing sisih lensa sing padha. Lensa cekung asring digunakake kanggo mbenerake rabun cedhak.

Lensa dirancang adhedhasar dawa fokus, yaiku jarak saka lensa menyang titik fokus. Dawane fokus nemtokake tingkat lentur cahya lan pembentukan gambar sing diasilake.

Sawetara istilah kunci sing ana gandhengane karo lensa optik kalebu:

Titik fokus: Titik ing ngendi sinar cahya konvergen utawa katon beda sawise ngliwati lensa. Kanggo lensa cembung, iku titik ing ngendi sinar paralel konvergen. Kanggo lensa cekung, iki minangka titik asale sinar divergen.

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

Aperture: Dhiameter lensa sing ngidini cahya nembus. Aperture sing luwih gedhe ngidini luwih akeh cahya sing bisa liwat, ngasilake gambar sing luwih padhang.

Sumbu optik: Garis tengah ngliwati tengah lensa jejeg lumahing.

Daya lensa: Diukur ing dioptri (D), daya lensa nuduhake kemampuan bias lensa. Lensa cembung nduweni kekuwatan positif, dene lensa cekung nduweni kekuwatan negatif.

Lensa optik wis ngrevolusi macem-macem bidang, saka astronomi nganti ilmu medis, kanthi ngidini kita ngamati obyek sing adoh, mbenerake masalah penglihatan, lan nindakake pencitraan lan pangukuran sing tepat. Dheweke terus duwe peran penting kanggo ngembangake teknologi lan eksplorasi ilmiah.
