APAKAH MAKSUD ULTRAMICROSCOPE dalam CORSICA?
Ultramicroscope
Sebuah ultramicroscope adalah mikroskop dengan sistem pencahayaan yang membolehkan melihat zarah-zarah kecil. Apabila diameter zarah berada di bawah atau berhampiran dengan panjang gelombang cahaya yang kelihatan, zarah tidak dapat dilihat dalam mikroskop cahaya dengan cara pencahayaan biasa. Sistem ultramicroscope didasarkan pada hamburan cahaya, bukan pantulan cahaya. Dalam sistem, zarah-zarah yang diperhatikan disebarkan dalam cecair atau gas koloid. Koloid itu diletakkan di dalam cahaya yang menyerap, kandang gelap, dan diterangi dengan rasuk konvergensi cahaya yang kuat memasuki dari satu sisi. Cahaya memukul zarah koloid akan bertaburan. Dalam perbincangan mengenai penyebaran cahaya, rasuk menumpu dipanggil "konak Tyndall". Adegan ini dilihat melalui mikroskop biasa yang ditempatkan pada sudut tepat ke arah cahaya lampu. Di bawah mikroskop, zarah-zarah individu akan muncul sebagai bintik-bintik kabur kecil cahaya bergerak tidak teratur. Tompok-tompok itu sememangnya kabur kerana penyebaran cahaya menghasilkan gambar-gambar kabur dari refleksi cahaya. Zarah berada dalam gerakan Brownian dalam kebanyakan jenis cecair dan gas koloid, yang menyebabkan pergerakan bintik-bintik.
Definisi ultramicroscope dalam kamus Corsica
Takrif ultramicroscope dalam kamus adalah mikroskop yang digunakan untuk mengkaji koloid, di mana sampel sangat diterangi dari sisi dan zarah koloid dilihat sebagai titik terang pada latar belakang gelap Juga dipanggil: mikroskop gelap bidang.
